Command Line Software Management

One of the nice things about a Debian-based Linux distribution is that it is easy to pull a piece of software onto your system from a repository using either apt-get or aptitude. Some may prefer to have a GUI but I find that the command line offers certain extra transparency that stops the “what’s it doing?” type of question. that’s never to say that the GUI-based approach hasn’t a place and I only go using it when seeking out a piece of software without knowing its aptitude-ready name. Interestingly, there are signs that Canonical may be playing with the idea of making Ubuntu’s Software Centre a full application management tool with updates and upgrades getting added to the current searching, installation and removal facilities. That well may be but it’s going to take a lot of effort to get me away from the command line altogether.

Fedora and openSUSE have their software management commands too in the shape of yum and zypper, respectively. The recent flurry of new operating system releases has had me experimenting with both of those distros on a real test machine. As might be expected, the usual battery of installation, removal and update activities are well served and I have been playing with software searching using yum too. What has yet to mature is in-situ distribution upgrading à la Ubuntu. In principle, it is possible but I got a black screen when I tried moving from openSUSE 11.1 to 11.2 within VirtualBox using instructions on the openSUSE website. Not wanting to wait, I reached for a Live CD instead and that worked a treat on both virtual and real machines. Being in an experiment turn of mind, I attempted the same to get from Fedora 11 to the beta release of its version 12. A spot of repository trouble got me using a Live CD in its place. You can perform an in-situ upgrade from a full Fedora DVD but the only option is system replacement when you have a Live CD. Once installation is out of the way, YAST can be ignored in favour of zypper and yum is good enough that Fedora’s GUI-using alternative can be ignored. It’s nice to see good transparent ideas taking hold elsewhere and may make migration between distros much easier too.

Rough?

Was it because Canonical and friends kept Ubuntu in such a decent state from 8.04 through to 9.04 that things went a little quiet in the blogosphere on the subject of the well-known Linux distribution? If so, 9.10 might be proving more of a talking point and you have to wonder if this is such a good thing with the appearance of Windows 7 on the scene. Looking on the bright side, 10.04 will be an LTS release so there is some chance that any rough edges that are on display now could be resolved by next April. Even so, it might have been better not to see anything so obvious at all.

In truth, Ubuntu always has had its gaps and I have seen a few of their ilk over the last two years. Of these, a few have triggered postings on here. In fact, issues with accessing the BBC iPlayer still bring a goodly number of folk to this website. That may just be a matter of grabbing RealPlayer, now helpfully available as a DEB package, from the requisite place on the web and ensuring that Ubuntu-Restricted-Extras is in place too but you have to know that in the first place. Even so, unexpected behaviours like Palimpsest seeing every partition on a disk as a different drive and SIL Raid mappings being seen for hard drives that used to live on the main home PC that bit the dust earlier this year; it only happens on one of the machines that I have running Ubuntu so it may be hardware thing and newly added hard drive uses none of the SIL mapping either. Perhaps more seriously (is it something that a new user should be encountering?), a misfiring variant of Brasero had me moving to K3b. Then UFRaw was sluggish in batch but that’s nothing that having a Debian VM won’t overcome. Rough edges like these do get you asking if 9.10 was ready for the big time while making you reluctant to recommend it to mainstream users like my brother.

The counterpoint to the above is that 9.10 includes a host of under the bonnet changes like the introduction of Ext4 hard drive formatting, Xsplash to allow the faster system loading to occur unseen and GNOME 2.28. To someone looking in from outside like me, that looks like a lot of work and might explain the ingress of the annoyances that I have seen. Add to that the fact that we are between Debian releases so things like the optimised packaging of ImageMagick or UFRaw may not be so high up the list of the things to do, especially with the more general speed optimisations that were put in place for 9.10. With 10.04 set to be an LTS release so I’d be hoping that consolidation is the order of the day over the next five or six months but it seems to be the inclusion of new features and other such progress that get magazine reviewers giving higher ratings (Linux Format has given it a mark of 9 out of 10). With the mooted inclusion of GNOME 3 and its dramatically different interface in 10.10, they should get their fill of that. However, I’d like to see some restraint for the take of a smooth transition from the familiar GNOME 2.x to the new. If GNOME 3 stays very like its alpha builds, then the question as how users will take to it arises. Of course, there’s some time yet before we see GNOME 3 and, having seen how the Ubuntu developers transformed GNOME 2.28, I wouldn’t be surprised if the impact of any change could be dulled.

In summary, my few weeks with Ubuntu 9.10 as my main OS have thrown up no major roadblocks that would cause me to look at moving elsewhere; Fedora would be tempting if that situation were to arise. The irritations that I have seen are more like signs of a lack of polish and remain peripheral to day-to-day working if you discount CD/DVD burning. To be honest, there always have been roughnesses in Ubuntu but has the lack of sizeable change spoilt us? Whatever about how things feel afterwards, big changes can mean new problems to resolve and inspire blog posts describing any solutions so it’s not all bad. If that’s what Canonical wants to see, they might get it and the year ahead looks as if it is going to be an interesting one after a recent quieter period.

Still able to build PC systems

This weekend has been something of a success for me on the PC hardware front. Earlier this year, a series of mishaps rendering my former main home PC unusable; it was a power failure that finished it off for good. My remedy was a rebuild using my then usual recipe of a Gigabyte motherboard, AMD CPU and crucial memory. However, assembling the said pieces never returned the thing to life and I ended up in no man’s land for a while, dependent on and my backup machine and laptop. That wouldn’t have been so bad but for the need for accessing data from the old behemoth’s hard drives but an external drive housing set that in order. Nevertheless, there is something unfinished about work with machines having a series of external drives hanging off them. That appearance of disarray was set to rights by the arrival of a bare bones system from Novatech in July with any assembly work restricted to the kitchen table.There was a certain pleasure in seeing a system come to life after my developing a fear that I had lost all of my PC building prowess.

That restoration of order still left finding out why those components bought earlier in the year didn’t work together well enough to give me a screen display on start-up. Having electronics testing equipment and the knowledge of its correct use would make any troubleshooting far easier but I haven’t got these. There is a place near to me where I could go for this but you are left wondering what might be said to a PC build gone wrong. Of course, the last thing that you want to be doing is embarking on a series of purchases that do not fix the problem, especially in the current economic climate.

One thing to suspect when all doesn’t turn out as hoped is the motherboard and, for whatever reason, I always suspect it last. It now looks as if that needs to change after I discovered that it was the Gigabyte motherboard that was at fault. Whether it was faulty from the outset or it came a cropper with a rogue power supply or careless with static protection is something that I’ll never know. An Asus motherboard did go rogue on me in the past and it might be that it ruined CPU’s and even a hard drive before I laid it to rest. Its eventual replacement put a stop to a year of computing misfortune and kick-started my reliance on Gigabyte. That faith is under question now but the 2009 computing hardware mishap seems to be behind me and any PC rebuilds will be done on tables and motherboards will be suspected earlier when anything goes awry.

Returning to the present, my acquisition of an ASRock K10N78 and subsequent building activities has brought a new system using an AMD Phenom X4 CPU and 4 GB of memory into use. In fact, I writing these very words using the thing. It’s all in a new TrendSonic case too (placing an elderly behemoth into retirement) and with a SATA hard drive and DVD writer. The new motherboard has onboard audio and graphics so external cards are not needed unless you are an audiophile and/or a gamer; for the record, I am neither. Those additional facilities make for easier building and fault-finding should the undesirable happen.

The new box is running the release candidate of Ubuntu 9.10 and it seems to be working without a hitch too. Earlier builds of 9.10 broke in their VirtualBox VM so you should understand the level of concern that this aroused in my mind; the last thing that you want to be doing is reinstalling an operating system because its booting capability breaks every other day. Thankfully, the RC seems to have none of these rough edges so I can upgrade the Novatech box, still my main machine and likely to remain so for now, with peace of mind when the time comes.

Booting from external drives

Sticking with older hardware may mean that you miss out on the possibilities offered by later kit and being able to boot from external optical and hard disk drives was something of which I learned only recently. Like many things, a compatible motherboard and my enforced summer upgrade means that I have one with the requisite capabilities.

There is usually an external DVD drive attached to my main PC so that allowed the prospect of a test. A bit of poking around in the BIOS settings for the Foxconn motherboard was sufficient to get it looking at the external drive at boot time. Popping in a CrunchBang Linux live DVD was all that was needed to prove that booting from a USB drive was a goer. That CrunchBang is a minimalist variant of Ubuntu helped for acceptable speed at system startup and afterwards.

Having lived off them while in home PC limbo, the temptation to test out the idea of installing an operating system on an external HD and booting from that is definitely there though I think that I’ll be keeping mine as backup drives for now. Still, there’s nothing to stop me installing an operating system onto of them and giving that a whirl sometime. Of course, speed constraints mean that any use of such an arrangement would be occasional but, in the event of an emergency, such a setup could have its uses and tide you over for longer than a Live CD or DVD. Having the chance to poke around with an alternative operating system as it might exist on a real PC has its appeal too and avoids the need for any partitioning and other chores that dual booting would require. After all, there’s only so much testing that can be done in a virtual machine.

Enabling DVD playback in Ubuntu 9.04

This information is scattered about the web but I decided to collect something together in one place in case it helps anyone else. Here are two commands that appeared to do the deed for me:

sudo apt-get install ubuntu-restricted-extras totem-xine libxine1-ffmpeg libdvdread4

sudo /usr/share/doc/libdvdread4/install-css.sh

The libdvdread piece is what sorts out encrypted disks and needs a two stage installation, hence the second command. For non-encrypted disks, ubuntu-restricted-extras might be all that’s needed if my experience is typical. Taking things further, Wim Wenders’ Buena Vista Social Club (Region 2 disk) worked when I tried it too. In the interests of completeness, I tried the command combination on a virgin 9.04 installation with restricted and multiverse repositories enabled. Along the way, I spied a whole raft of helper components being set in place and things worked like I would have expected with the aforementioned DVD afterwards. As with anything related to computing, your mileage may vary and, for more information, you can take a look here.
