Though I use only the command line to do system updates, I still got system restart messages every time a new kernel version was installed. While they can be helpful, I actually prefer to be left to my own devices when it comes to restarting a system and I may have a something running at the time that I do not wish to interrupt.
In Ubuntu GNOME 13.10 and before, there was no sign of these messages so I decided to see if I could go nag free again. The responsible application is called Update Notifier and I tried seeing if I could remove it but that act has a major impact of the system so it was not a useful way to go.
As it happens, it is an application that starts up automatically at computer boot time but there was no sign of an entry for it in the Startup Applications Preferences screen (started using from the command line using gnome-session-properties). The for this is that there is flag called NoDisplay in the relevant autostart shortcut in /etc/xdg/autostart/ that stops it appearing in the aforementioned settings screen when set to true. The trick then is to set it to false and the following command (broken over two lines for sake of display and quotes could need replacing when you issue the command too) does the trick for all such hidden start-up applications:
sudo sed -i ‘s/NoDisplay=true/NoDisplay=false/g’
What the above does is that sed goes into every file and changes NoDisplay=true to NoDisplay=false in each file with the desktop extension. When that has completed, there are more entries in Startup Applications Preferences and Update Notifier can be deselected in order to stop it starting. Removing the relevant .desktop file would be a more permanent change but this one will do me, especially since no more of those pesky restart messages appear anymore. My regularity when it came to system updates meant that the update messages never appeared anyway and I tend to shut down my system at the end of every day so the updates will be picked up too so all should be well.
When I recently did my usual system update for the stable version Ubuntu GNOME, there were some updates pertaining to apt and the process failed when I executed the following command:
sudo apt-get upgrade
Usefully, some messages were issued and here’s a flavour:
Setting up apt (0.9.9.1~ubuntu3.1) …
ERROR: Can’t find the archive-keyring
Is the ubuntu-keyring package installed?
dpkg: error processing apt (--configure):
subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1)
Some searching on the web revealed that the problem was that there were no files in /usr/share/keyring when there should have been and I had not removed them myself so I have no idea how they disappeared. Various remedies were tried and any that needed software installed were non-starters because apt was disabled by the lack of keyring files. The workaround that restored things for me was to take a copy of the files in /usr/share/keyring from an Ubuntu GNOME 14.04 installation in a VirtualBox VM and copy them in to the same location in its Ubuntu GNOME 13.10 host. For those without such resources, I have packaged them in a zip file below. Other remedies like Y PPA also were suggested where I was reading but that software package needed installing beforehand so it was little use to me when the likes of Synaptic were disabled. If there are other remedies that do not involve an operating system re-installation, I would like to know about them too as well as possible causes for the file loss in the first place and how to avoid these.
Last week, Microsoft released a preview of Windows 8.1 and some hailed the return of the Start button but the reality is not as simple as that. Being a Linux user, I am left wondering if ideas have been borrowed from GNOME Shell instead of putting back the Start Menu like it was in Windows 7. What we have got is a smoothing of the interface that is there for those who like to tweak settings and not available be default. GNOME Shell has been controversial too so borrowing from it is not an uncontentious move even if there are people like me who are at home in that kind of interface.
What you get now is more configuration options to go with the new Start button. Right clicking on the latter does get you a menu but this is no Start Menu like we had before. Instead, we get a settings menu with a “Shut down” entry. That’s better than before, which might be saying something about what was done in Windows 8, and it produces a sub-menu with options of shutting down or restarting your PC as well as putting it to sleep. Otherwise, it is place for accessing system configuration items and not your more usual software, not a bad thing but it’s best to be clear about these things. Holding down the Windows key and pressing X will pop up the same menu if you prefer keyboard shortcuts and I have a soft spot for them too.
The real power is to be discovered when you right click on the task bar and select the Properties entry from the pop-up menu. Within the dialogue box box that appears, there is the Navigation tab that contains a whole plethora of interesting options. Corner navigation can be scaled back to remove the options of switching between applications at the upper left corner or getting the charms menu from the upper right corner. Things are interesting in the Start Screen section. This where you tell Windows to boot to the desktop instead of the Start Screen and adjust what the Start button gives you. For instance, you can make it use your desktop background and display the Start Screen Apps View. Both of these make the new Start interface less intrusive and make the Apps View feel not unlike the way GNOME Shell overlays your screen when you hit the Activities button or hover over the upper left corner of the desktop.
It all seems rather more like a series of little concessions and not the restoration that some (many?) would prefer. Classic Shell still works for all those seeking an actual Start Menu and even replaces the restored Microsoft Start button too. So, if the new improvements aren’t enough for you, you still can take matters into your own hands until you start to take advantage of what’s new in 8.1.
Apart from the refusal to give us back a Windows 7 style desktop experience, we now have a touchscreen keyboard button added to the taskbar.So far, it always appears there even when I try turning it off. For me, that’s a bug and it’s something that I’d like to see fixed before the final release.
All in all, Windows 8.1 feels more polished than Windows 8 was and will be a free update when the production version is released. My explorations have taken place within a separate VMware virtual machine because updating a Windows 8 installation to the 8.1 preview is forcing a complete re-installation on yourself later on. There are talks about Windows 9 now but I am left wondering if going for point releases like 8.2, 8.3, etc. might be a better strategy for Microsoft. It still looks as if Windows 8 could do with continual polishing before it gets more acceptable to users. 8.1 is a step forward and more like it may be needed yet.
