Ubuntu – Long Term Support

One item of particular interest with Ubuntu is their development schedule. Because a typical Linux distribution is composed of many applications from many different parties, the Ubuntu developers do not directly control or develop a lot of the software included in Ubuntu. Furthermore Ubuntu tries to be a complete desktop environment rather than just an operating system, which means it includes a wider variety of software than what’s found in Windows and Mac OS X.

What this amounts to is that Ubuntu needs to both provide future patch support for included applications, and it needs to compensate for the fact that they don’t develop many of these programs. Coupled with this is the fact that 2nd party application development is not necessarily synchronized to Ubuntu’s release schedule and some applications (and the kernel itself) can have a rather rapid development rate.

Trying to deal with all of these factors, Ubuntu has settled on two classes of releases. Every 6 months – in October and April – Ubuntu takes what’s ready and releases a new version of the OS. For 1st party material this is tied with some goal for the release (such as replacing the audio daemon) while for 3rd party software this may be as simple as grabbing the latest version. This puts regular Ubuntu versions in an unusual position when trying to classify them – it’s significantly more than a Mac OS X point update, still more than a Windows service pack, and yet a single release generally encompasses less than a new version of either OS. But at the same time, there’s no guarantee that any given release of Ubuntu won’t break software compatibility or binary driver compatibility, which puts it up there with major OS releases.

Furthermore because of the need to provide security updates for all these different programs in all of these different versions, Ubuntu has a very short support cycle, and in that cycle only bug fixes and security updates will be issued, software is not otherwise changed as it’s intended to represent a stable platform. A regular release is only supported for 1.5 years; which for example means support for 7.10 Gutsy, the immediate predecessor to 8.04 Hardy Heron, expired in April. This pushes new versions of Ubuntu back towards the idea of them being closer to a service pack or a point release. In essence, it’s intended that everyone using regular versions of Ubuntu will stick to a relatively rapid upgrade treadmill.

But this obviously doesn’t work for everyone, which results in there being two classes of Ubuntu. What we’re looking at today, 8.04, is what Ubuntu calls a long term support (LTS) release. Every 2 years a version of Ubuntu is labeled as a LTS release, which entails a much greater effort on the developer’s part to support that edition of the OS. The standard support period is 3 years instead of 1.5 years, and for the server edition of the OS that becomes 5 years.

This makes the LTS releases more comparable to Mac OS X and Windows, both of which have long support periods in excess of 3 years. This is also why we’re starting with a review of Hardy, in spite of it being over a year old now, because it’s the current LTS release. Regular short-support Ubuntu releases have their place, but they are not intended for long-term use. Coming from Windows or Mac OS X, a LTS release is the comparable equivalent.

Operating System Mainstream Support Extended Support
Windows 5 years 5 additional years
Ubuntu 1.5 years None
Ubuntu LTS 3 years None
Mac OS X So long as it's the newest OS So long as it's one version behind

Unfortunately, in spite of the LTS designation, not all of the applications in a LTS release are intended to be used for such a long period of time, or are their developers willing to support them for that length of time. If we take Firefox for example, the last Ubuntu LTS release, 6.06 Dapper, shipped with Firefox 1.5. Mozilla very quickly ended support for Firefox 1.xx after Firefox 2 shipped, and now you can’t even get support for 2.xx now that 3.xx has been out for quite some time. This leaves the Ubuntu developers in charge of supplying security updates for the older versions of Firefox they still support, which while better than the alternative (no security patches) isn’t necessarily a great solution.

The Ubuntu developers have done a good job of staying on top of the matter (they just published a new 1.5 security patch as recently as last month) but it highlights the fact that the Ubuntu developers do not always have the resources to maintain both a stable platform and the necessary security updates. So while an LTS release is supposed to be supported for 3 years, in reality not every component is going to make it that long.

Digging through the bugs list for Dapper and Hardy, I get the impression that these kinds of cracks only occur on less-used software (particularly that which is not part of the default install, such as VLC), so an option for users who need to stick with the base OS for the entire life of a LTS release, but don’t mind upgrading a few applications can go that route and cover all of their bases. Unfortunately this is easier said than done, and we’ll get to why that is when we discuss the package manager.

What this amounts to is that if you’re the kind of person that intends to run a computer and an OS for a very long period of time – say on the scale of XP, which turns 8 this year – Ubuntu likely isn’t a good fit for you.

It’s Secure What’s the Value of Technical Support, Anyhow?

    for your time spent on writing this article. I've made the jump to from Windows to Ubuntu (and Xubuntu for my older computers) back around 7.10 and 8.04 and I went through some of the headaches in adjusting to Ubuntu, but I eventually solved all of them and I'm quite settled in now.

    One comment about finding help in the form of command line instructions, rather than GUI instructions. GUI instructions for Ubuntu would not be useful for Kubuntu or Xubuntu, since they use different window managers. The command line solutions usually work for all three.

    Also, boot times were noticeably improved in 9.04. Perhaps you can run a quick retest on it.

    And you CAN install stuff when using the live CD. I've installed a couple of temperature monitoring utilities when I was stress testing my motherboard.

    Finally, thanks again for writing such a thorough look into your Ubuntu experiences. It was a great read in seeing how far Ubuntu has come and what it still lacks.

    Yeah, you can set the APT sources to use a CD. There is an option for it 'system' > 'administor' > 'software source', or you can edit the /etc/apt/sources.list file

    [quote]since SMB is the predominant protocol for consumer file server gear, it’s a fair test of such use.[/quote]

    While this comment is not false, it presents a lazy approach to comparison; it's a one-sided contest, and Linux, pitted against Windows on home turf, doesn't stand much of a chance.

    You as much as acknowledge this in the article, so why not provide some counterpoint? For example, consumer file server gear, even if it supports SMB almost ubiquitously, is usually *nix-based. So instead of just showing Windows and Linux clients interacting with Windows servers, show them interacting with *nix servers as well. Do some NFS transfers as well; NFS is well supported in consumer NAS these days.

    You also really missed the boat on the video drivers. 8.04 was not the first Ubuntu release to include the Restricted Drivers Manager (known simply as "Hardware Drivers" in later releases). This handy app will identify hardware, such as AMD and NVIDIA GPUs, that can take advantage of proprietary drivers, and will offer to to install the same via synaptic (APT) with just a click of the mouse. No CLI, no headaches.

    Still, a thorough review, and generally well-researched. I'm looking forward to the 9.04 follow-up.

    Since you mentioned hardware HD decoding, I recommend taking a look at smplayer from the testing ppa (https://launchpad.net/~rvm/+archive/testing)">https://launchpad.net/~rvm/+archive/testing). Unfortunately vdpau doesn't work with the nvidia blobs in the default Ubuntu repos, but I believe there's a PPA providing vdpau-compatible blobs for anybody not wanting to do CLI installs.

    This isn't Linux pitted against Windows on home turf, it's Linux pitted against Windows in the real world.

    Well, no doubt SMB is the dominant method of sharing files for consumers in general. Obviously comparing Linux to Windows makes sense in a world where Windows is the incumbent, but it's not the whole story.

    I hope Part 2 will address some of the objective benefits of Ubuntu, and not fall into the trap of "worse because it's not the same as Windows".
  • VaultDweller - Wednesday, August 26, 2009 - link

    I agree in principle, but there has to be a distinction between "Worse because it's not compatible with Windows," "Worse because it's not as easy as Windows," and "Worse because it's not the same as Windows." Die-hard *nix advocates tend to dismiss the first two as if they were the latter, and this tends to undermine their argument.

    Also, in some cases "Worse because it's not the same as Windows" can be a valid point, because the public has been trained to the point that the Windows way is the "intuitive" way. Of course, this isn't truly intuitive, as people who learned Linux first would find Linux methodologies more intuitive - but that's largely a moot point, as that's not the reality we live in today. You could say the same thing about the color red - in the western world, when we see red we can intuitively guess that it means Stop, or Warning, or Error, etc. The fact that this is not an understanding we're born with but rather a socially acquired intuition does not mean it would be any easier to suddenly change the color of traffic lights and expect people to adjust without problems.

    All of the NAS gear I can get my hands on is either SMB only, or is a Time Capsule which is SMB + AFP. I don't have anything that does NFS, which isn't so much a comment on testing (I could always set up another box) as it is usefulness. NFS just isn't common on consumer gear; SMB is a more important metric if you're looking at file transfer performance, because that's what most people are going to be working with. This doesn't preclude doing NFS at a later time though.

    And the Restricted Drivers Manager is limited to the drivers in the Hardy repository, which means they're a year+ out of date.
  • amrs - Wednesday, September 30, 2009 - link

    Interestingly, if one checks the SmallNetBuilder NAS charts, it looks like out of 87 NAS devices, 49 have NFS. 56% in other words. And you say NFS isn't common? Really now? Seems a little biased to me.

    While a lot of your issues have complicated solutions or lengthy technical backstories I can solve your complaint of smb shares mounted in nautilus not being useful in non-gtk applications in one simple command (or as you seem to hate commands the gui can do it too).

    theory: make a symlink to the directory nautilus mounts to so it can be easily accessed. Symlinks to directories or files are transparently (to users and applications) identical to the location they refer to. Windows doesn't have symlinks (only useless shortcuts) so it isn't surprising you were not aware to do it.

    howto: gvfs uses the directory /home/$USER/.gvfs as a mount point so link to it:
    ln -s ~/.gvfs ~/linkname

    howto gui: in nautilus go to your home folder then choose view -> show hidden files. Right click on .gvfs and choose make link. Then you can rename the link to whatever you want and hide hidden files again.

    hint: symlinks are your best friend. My home dir is littered with links to places on the filesystem I visit a lot to avoid a lot of clicking/typing
  • Ryan Smith - Wednesday, August 26, 2009 - link

    I suddenly feel very humiliated...

    The symlink is a very elegant solution, I'm embarrassed I didn't think of that myself. It's a bit of a lousy solution in that there even needs to be a solution, but as far as things go that's a very insightful suggestion.
