Adventures & experiences in contemporary technology
There remain people who advise those on Windows 7 or 8.x to hold fire on upgrading to Windows 10. Now that the free upgrade no longer is available, that advice may hold more weight than it did. Even so, there are those among us who jumped ship who do not mind having the latest versions of things at no monetary cost to see what is available and I must admit to being one of those.
After all, I do have a virtual machine with a pre-release version of the next update to Windows 10 installed on there to see what might be coming our way and to get a sense of what changes that may bring so that I am ready for those. Otherwise, I usually am happy to wait but I noticed that the Windows 10 Anniversary Update only came to my HP Pavilion dm4 laptop and not other machines with Windows 10 installed so I started to wonder why there was a lag when it came to automatic upgrades.
So that these things do not arrive when it is least convenient, I took advantage of a manual method in order to choose my timing. This did not involve installation from a disk image but was in-situ. The first part of the process is standard enough in that the Settings app was started and the Update & security item chosen. That dropped me onto the Windows Update and I first clicked on the Check for updates button to see what would happen. When nothing came of that, the Learn more link was clicked to bring me onto part of the Microsoft support website where I found that the Windows 10 Anniversary Update installer could be downloaded so I duly did just that.
Running it produced a screen asking whether or not I wanted to proceed. Since I wanted to go ahead, the appropriate button was clicked and the machine left alone until the process complete. Because the installer purely is a facilitator, the first stage is to download the rest of the files needed and that will take a while on any connection. Once downloading was completed, the actual process of installation commenced with several restarts before a log-in screen was again on offer. On logging in to the machine, the last part of the process started.
The process took quite a while but seemingly worked without a hitch. If there was anything that I needed to do, it was the re-installation of VirtualBox Guest Additions to restore access to shared folders as well as dealing with a self-inflicted irritation. Otherwise, I have found that previously installed software worked as expected and no file has been missed. Waiting a while may have had its advantages too because initial issues with the Anniversary Update will have been addressed but it is best not to leave it too long or you could have the feeling of being forgotten. A happy balance needs striking.
It was an article in a magazine that revealed these legal BitTorrent download sites to me, so I thought that I’d keep them on file for future reference while also sharing them with others who might need them. As far as I am aware, they are all legal in that no copyrighted material is on there. If that changes, I am happy to know and make amendments as needed.
My own interest in torrents arises from their being a convenient way to download installation disk images for Linux distributions, and at least one of the entries is devoted to just that. However, the distribution also lends itself to movies along with music and books, so that is reflected below too. With regard to downloading actual multimedia content, there is so much illegal downloading that a list like this is needed and has blackened the reputation of BitTorrent too because it only ever was conceived as a means for distributing large files in a peer-to-peer manner without the use of a single server. Of course, any use can be found for a technology, and it never has to be legal or morally acceptable either.
BitTorrent may have got some bad press due to its use for downloading copyrighted material such as music and movies but it does have its legitimate uses too. In my case, many a Linux distro has been downloaded in this way and it does take the weight off servers by distributing the load across users instead.
Speaking of Linux, my general choice of client has been Transmission and there are others. In the Windows world, there is a selection that includes BitTorrent, Inc. themselves. However, many favour uTorrent (or μTorrent) so that’s the one that I tried and there free and subscription-based options. To me, the latter feels like overkill when an eternal licence could be made available as an easy way to dispatch the advertisements on display in the free version.
As much as I appreciate the need for ads to provide revenue to a provider of otherwise free software, they do need to be tasteful and those in uTorrent often were for dating websites that had no scruples about exposing folk to images that were unsuitable for a work setting. Those for gaming websites were more tolerable in comparison. With the non-availability of an eternal licence option, I was left pondering alternatives like qBittorrent instead. That is Free Software too so it does have that added advantage.
However, I uncovered an article on LifeHacker that sorted my problem with uTorrent. The trick is to go into Options > Preferences via the menus and then go to the Advanced section in the dialogue box that appears. In there, go looking for each of the following options and set each one to false in turn:
In practice, I found some of the above already set to false and another missing but set those that remained from true to false cleaned up the interface so I hope never to glimpse those unsuitable ads again. The maker of uTorrent need to look at the issue or revenue could get lost and prospective users could see the operation as being cheapened by what is displayed. As for me, I am happy to have gained something in the way of control.
Installing the latest version of Citrix Receiver (13.0 at the time of writing) on 64-bit Ubuntu should be as simple as downloading the required DEB package and double-clicking on the file so that Ubuntu Software Centre can work its magic. Unfortunately, the 64-bit DEB file is faulty so that means that the Ubuntu community how-to guide for Citrix still is needed. In fact, any user of Linux Mint or another distro that uses Ubuntu as its base would do well to have a look at that Ubuntu link.
For sake of completeness, I still am going to let you in on the process that worked for me. Once the DEB file has been downloaded, the first task is to creating a temporary folder where the DEB file’s contents can be extracted:
mkdir ica_temp
With that in place, it then is time to do the extraction and it needs two commands with the second of these need to extract the control file while the first extracts everything else.
sudo dpkg-deb -x icaclient- ica_temp
sudo dpkg-deb --control icaclient- ica_temp/DEBIAN
It is the control file that has been the cause of all the bother because it refers to unavailable dependencies that it really doesn’t need anyway. To open the file for editing, issue the following command:
sudo gedit ica_temp/DEBIAN/control
Then change line 7 (it should begin with Depends:) to: Depends: libc6-i386 (>= 2.7-1), lib32z1, nspluginwrapper. There are other software packages in there that Ubuntu no longer supports and they are not needed anyway. With the edit made and the file saved, the next step is to build a new DEB package with the corrected control file:
dpkg -b ica_temp icaclient-modified.deb
Once you have the package, the next step is to install it using the following command:
sudo dpkg -i icaclient-modified.deb
If it fails, then you have missing dependencies and the following command should sort these before a re-run of the above command again:
sudo apt-get install libmotif4:i386 nspluginwrapper lib32z1 libc6-i386
With Citrix Receiver installed, there is one more thing that is needed before you can use it freely. This is to put Thawte security certificate files into /opt/Citrix/ICAClient/keystore/cacerts. What I had not realised until recently was that many of these already are in /usr/share/ca-certificates/mozilla and linking to them with the following command makes them available to Citrix receiver:
sudo ln -s /usr/share/ca-certificates/mozilla/* /opt/Citrix/ICAClient/keystore/cacerts/
Another approach is to download the Thawte certificates and extract the archive to /tmp/. From there they can be copied to /opt/Citrix/ICAClient/keystore/cacerts and I copied the Thawte Personal Premium certificate as follows:
sudo cp /tmp/Thawte Root Certificates/Thawte Personal Premium CA/Thawte Personal Premium CA.cer /opt/Citrix/ICAClient/keystore/cacerts/
Until I found out about what was in the Mozilla folder, I simply picked out the certificate mentioned in the Citrix error message and copied it over like the above. Of course, all of this may seem like a lot of work to those who are non-tinkerers and I have added a repaired 64-bit DEB package that incorporates all of the above and should not need any further intervention aside from installing it using GDebi, Ubuntu’s Software Centre, dpkg or anything else that does what’s needed.
With the release of Windows 8 around this time last year, I thought that the full retail version that some of us got for fresh installations on PC’s, real or virtual, had become a thing of the past. In fact, it did seem that every respecting technology news website and magazine was saying just that. The release that you would buy from Microsft or from mainstream computer stores was labelled as an upgrade. That made it look as if you needed the OEM or System Builder edition for those PC’s that needed a new Windows installation and that the licence that you bought was then attached to the machine from when it got installed on there.
As is usual with Microsoft, the situation is less clear cut than that. For instance, there was some back-pedalling to allow OEM editions of Windows to be licensed for personal use on real or virtual PC’s. With Windows & and its predecessors, it even was possible to be able to install afresh on a PC without Windows by first installing on inactivated copy on there and then upgrading that as if it was a previous version of Windows. Of course, an actual licence was of the previous version of Windows was needed for full compliance if not the actual installation. At times, Microsoft muddies waters so as to keep its support costs down.
Even with Microsoft’s track record in mind, it still did surprise me when I noticed that Amazon was selling what appeared to be full versions of both Windows 8.1 and Windows 8.1 Pro. Having set up a 64-bit VirtualBox virtual machine for Windows 8.1, I got to discovering the same for software purchased from the Microsoft web site. However, unlike the DVD versions, you do need an active Windows installation if you fancy a same day installation of the downloaded software. For those without Windows on a machine, this can be as simple as downloading either the 32-bit or the 64-bit 90 day evaluation editions of Windows 8.1 Enterprise and using that as a springboard for the next steps. This not only be an actual in-situ installation but there options to create an ISO or USB image of the installation disk for later installation.
In my case, I created a 64-bit ISO image and used that to reboot the virtual machine that had Windows 8.1 Enterprise on there before continuing with the installation. By all appearances, there seemed to be little need for a pre-existing Windows instance for it to work so it looks as if upgrades have fallen by the wayside and only full editions of Windows 8.1 are available now. The OEM version saves money so long as you are happy to stick with just one machine and most users probably will do that. As for the portability of the full retail version, that is not something that I have tested and I am unsure that I will go beyond what I have done already.
My main machine has seen a change of motherboard, CPU and memory so it could have de-activated a pre-existing Windows licence. However, I run Linux as my main operating system and, apart possibly from one surmountable hiccup, this proves surprisingly resilient in the face of such major system changes. For running Windows, I turn to virtual machines and there were no messages about licence activation during the changeover either. Microsoft is anything but confiding when it comes to declaring what hardware changes inactivate a licence. Changing a virtual machine from VirtualBox to VMware or vice versa definitely so does it so I tend to avoid doing that. One item that is fundamental to either a virtual or a real PC is the mainboard and I have seen suggestions that this is the critical component for Windows licence activation and it would make sense if that was the case.
However, this rule is not hard and fast either since there appears to be room for manoeuvre should your PC break. It might be worth calling Microsoft after a motherboard replacement to see if they can help you and I have seen that it is. All in all, Microsoft often makes what appear to be simple rules only to override them when faced with what happens in the real world. Is that why they can be unclear about some matters at times? Do they still hanker after how they want things to be even when they are impossible to keep like that?
While I have a previous posting from 2009 that discusses adding Microsoft’s Core Fonts to the then current version of Fedora, it did strike me that I hadn’t laid out the series of command that were used. Instead, I referred to an external and unofficial Fedora FAQ. That’s still there but I also felt that I was leaving things a little to chance given how websites can disappear quite suddenly.
Even after next to four years, it still amazes me that you cannot install Microsoft’s Core Fonts in Fedora as you would in Ubuntu, Linux Mint or even Debian. Therefore, the following series of steps is as necessary now as it was then.
The first step is to add in a number of precursor applications such as wget for command line file downloading from websites, cabextract for extracting the contents of Windows CAB files, rpmbuild for creating RPM installers and utilities for the XFS file system that chkfontpath needs:
sudo yum -y install rpm-build cabextract ttmkfdir wget xfs
Here, I have gone with terminal commands that use sudo but you could become the superuser (root) for all of this and there are those who believe you should. The -y switch tells yum to go ahead with prompting you for permission before it does any installations. The next step is to download the Microsoft fonts package with wget:
sudo wget http://corefonts.sourceforge.net/msttcorefonts-2.0-1.spec
Once that is done, you need to install the chkfontpath package because the RPM for the fonts cannot be built without it:
sudo rpm -ivh http://dl.atrpms.net/all/chkfontpath
Once that is in place, you are ready to create the RPM file using this command:
sudo rpmbuild -ba msttcorefonts-2.0-1.spec
After the RPM has been created, it is time to install it:
sudo yum install --nogpgcheck ~/rpmbuild/RPMS/noarch/msttcorefonts-2.0-1.noarch.rpm
When installation has completed, the process is done. Because I used sudo, all of this happened in my own home area so there was a need for some housekeeping afterwards. If you did it by becoming the root user, then the files would be there instead and that’s the scenario in the online FAQ.
Over the course of a year, I end up visiting Ireland a few times so I decided to invest in a Meteor PAYG broadband stick to see how I’d get on with it. For €20, your can get a 30-day pass with 7.5 GB downloading capacity, a more generous offer than you’d get with some UK mobile networks (T-Mobile really come to mind here). Signal strength was strong wherever I tried it too with 3G being available so long as you are in the right place with EDGE being the lowest that I got otherwise. Download speeds are good too so it turned out to be a good investment of €30 to get the Huawei E173 USB dongle (I had a T-Mobile one of these before and it no longer works so I am keeping an eye on reliability with this one; the design seems a little different and I am getting OK so far) and €20 of credit that comes with it. After all, anything’s better than the punitive roaming rates that UK providers charge.
On the surface of it, this probably sounds a very strange thing to do: choose Linux Mint because they plan to stick with their current desktop interface for the foreseeable future and then stick a brand new one on there. However, that’s what last weekend’s dalliance with Fedora 15 caused. Not only did I find that I could find my way around GNOME Shell but I actually got to like it so much that I missed it on returning to using my Linux Mint machine again.
The result was that I started to look on the web to see if there was anyone else like me who had got the same brainwave. In fact, it was Mint’s being based on Ubuntu that allowed me to get GNOME 3 on there. The task could be summarised as involving three main stages: getting GNOME 3 installed, adding extensions and adding the Cantarell font that is used by default. After these steps, I gained a well-running GNOME 3 desktop running on Linux Mint and it looks set to stay that way unless something untoward has yet to emerge.
Installing GNOME 3
The first step is to add the PPA repository for GNOME 3 using the following command:
sudo add-apt-repository ppa:gnome3-team/gnome3
The, it was a case of issuing my usual update/upgrade command:
sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade
When that had done its thing and downloaded and installed quite a few upgrades along the way, it was time to add GNOME Shell using this command:
sudo apt-get install gnome-shell
When that was done, I rebooted my system to be greeted by a login screen very reminiscent of what I had seen in Fedora. While compiling this piece, I noticed that GNOME Session could need to be added before GNOME Shell but I do not recall doing so myself. Maybe dependency resolution kept any problems at bay, but there weren’t any issues that I could remember beyond things not being configured as fully as I would have liked without further work. For the sake of safety, it might be a good idea to run the following before adding GNOME Shell to your PC.
sudo apt-get install gnome-session && sudo apt-get dist-upgrade
Configuration and Customisation
Once I had logged in, the desktop that I saw wasn’t at all unlike the Fedora one and everything seemed stable too. However, there was still work to do before I was truly at home with it. One thing that was needed was the ever useful GNOME Tweak Tool. This came in very handy for changing the theme that was on display to the standard Adwaita one that caught my eye while I was using Fedora 15. Adding buttons to application title bars for minimising and maximising their windows was another job that the tool allowed me to do. The command to get this goodness added in the first place is this:
sudo apt-get install gnome-tweak-tool
The next thing that I wanted to do was add some extensions so I added a repository from which to do this using the command below. Downloading them via Git and compiling them just wasn’t working for me so I needed another approach.
sudo add-apt-repository ppa:ricotz/testing
With that is place, I issued the following commands to gain the Dock, the Alternative Status Menu and the Windows Navigator. The second of these would have added a shutdown option in the me-menu but it seems to have got deactivated after a system update. Holding down the ALT key to change the Suspend entry to Power off… will have to do me for now. Having the dock is the most important and that, thankfully, is staying the course and works exactly as it does for Fedora.
sudo apt-get install gnome-shell-extensions-dock
sudo apt-get install gnome-shell-extensions-alternative-status-menu
sudo apt-get install gnome-shell-extensions-windows-navigator
Adding Cantarell
The default font used by GNOME 3 in various parts of its interface is Cantarell and it was defaulting to that standard sans-serif font on my system because this wasn’t in place. That font didn’t look too well so I set to tracking the freely available Cantarell down on the web. When that search brought me to Font Squirrel, I downloaded the zip file containing the required TTF files. The next step was to install them and, towards that end, I added Fontmatrix using this command:
sudo apt-get install fontmatrix
That gave me a tool with a nice user interface but I made a mistake when using it. This was because I (wrongly) thought that it would copy files from the folder that I told the import function to use. Extracting the TTF files to /tmp meant that would have had to happen, but Fontmatrix just registered them instead. A reboot confirmed that they hadn’t been copied or moved at all and I had rendered the user interface next to unusable through my own folly; the default action on Ubuntu and Linux Mint is that files are deleted from /tmp on shutdown. The font selection capabilities of the GNOME Tweak Tool came in very handy for helping me to convert useless boxes into letters that I could read.
Another step was to change the font line near the top of the GNOME Shell stylesheet (never thought that CSS usage would end up in places like this…) so that Cantarell wasn’t being sought and text in sans-serif font replaced grey and white boxes. The stylesheet needs to be edited as superuser, so the following command is what’s needed for this and, while I used sudo, gksu is just as useful here if it isn’t what I should have been using.
sudo gedit /usr/share/gnome-shell/theme/gnome-shell.css
Once I had extricated my system from that mess, a more conventional approach was taken and the command sequence below was what I followed, with extensive use of sudo to get done what I wanted. A new directory was created and the TTF files copied in there.
cd /usr/share/fonts/truetype
sudo mkdir ttf-cantarell
cd ttf-cantarell
sudo mv /tmp/*.ttf .
To refresh the font cache, I resorted to the command described in a tutorial in the Ubuntu Wiki:
sudo fc-cache -f -v
Once that was done, it was then time to restore the reference to Cantarell in the GNOME Shell stylesheet and reinstate its usage in application windows using the GNOME Tweak Tool. Since then, I have suffered no mishap or system issue with GNOME 3. Everything seems to be working quietly and I am happy to see that replacement of Unity with the GNOME Shell will become an easier task in Ubuntu 11.10, the first alpha release of which is out at the time of my writing these words. Could it lure me back from my modified instance of Linux Mint yet? While I cannot say that I am sure of those but it certainly cannot be ruled out at this stage.
