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?

    Maybe I'm missung something but this appears to be a new article.
    Why are you reviewing a year-old version of Ubuntu? there's been nearly 3 releases since that (Ubuntu is on 9.04 now with 9.10 coming very soon).
    Its important to review the most recent version as Ubuntu is totally unlike the Microsoft world in tnat new releases are frequent (Every 6 months) and have real practical improvements.

    I couldn't help myself, but...

    RTFA!!

    :-D

    PS: if you read the article, you will also get the joke ;)

    Great article. I look forward to reading the follow up.

    One comment on security that I would like to make. The commercial Linux vendors (IBM, Novell, Redhat, etc.) are all VERY dedicated to ensuring Linux security, as many/all of their server products use Linux, and changes they make will filter back down to the Linux desktop community. This is something that OSX does not have to nearly the same degree.

    My experience with running Linux on the desktop sounds pretty much the same as yours.
    -Games killed it in general. I don't usually have a top of the line system. So, I'm usually pushing my computer its limits to run newer games under Windows. Also, I hate dual booting, and most of the FOSS I use is available as a compiled binary for Windows.
    -Drivers killed it in one specific instance with an older laptop, as I never got NdisWrapper (required for my wifi cards Windows drivers) to run better than intermittently. I spent way to much time messing with it.

    [quote]and for the price you’re only giving up official support.[/quote]

    Ubuntu doesn't have free official support, but neither does Microsoft. Apple does give 90 days free phone support, to their credit, but after that you have to pay.

    You can always hire an expert (from ms, or apple, or a third party) to help you, but that's also true with ubuntu, though I expect there are fewer such experts to be found.

    MS, Apple, and Ubuntu all offer free web-based help, both community maintained and "officially" maintained.

    So I think it's misleading to imply that going from Windows or Mac to Ubuntu means you're downgrading your support options. People overestimate just how "supported" their operating systems are. Also, Linux / Ubuntu releases fixes and updates much more quickly than Apple or MS, so your chances of hitting a bug is lower in the first place. (MS maintains a huge knowledgebase of bugs they haven't bothered to fix yet and might have a workaround for - but I hardly see that as a positive).

    I'm probably being too hard on Apple here. The genius bar offers free 15 minute appointments to diagnose problems and offer software tips / advice.

    I'd say apple has the best "official" support, followed by a fuzzy tie between ubuntu and microsoft.

    While I have used computers for 20 years or more, I am not a techie. I am much more interested an experience that "just works".

    When Vista came out I decided to explore the Linux desktop world. I have been using it as my primary system (still keep the dual boot option for XP) for just under 2 years.

    I agree that "free" and security are big considerations for moving to a Linux desktop environment. However, there are some other items (and you might class them under security) that I like - because of the file structure, you don't have to periodically defrag your system. Both systems have a lot of updates, but so far I have not gotten the feeling that my Ubuntu system is gradually slowing down and clogging up with a lot of useless files (you don't see a lot of adds for such utilities as Registry Cleaners:). I no longer experience the MS ripple effect - when MS sneezes, other Windows apps may get a cold.

    That is not to say that there cannot be issues. My pet peeve has been that my sound has disappeared on a couple of occassions after downloading updates. Using Google, and the Ubuntu documentation, I have been able to get it back up - but wish that wouldn't happen. But Windows updates can on occassion cause some issues.

    I think you made a very valid point about the issue of tech support. Google has made a big difference in problem solving.

    Enjoyed your review.

    I've tried using Linux (usually Ubuntu) as a full replacement desktop on and off for the last few years. I've gone back to Windows every time after a while. Some key points:

    1. For my desktop usage, there honestly isn't anything that Linux does better, in terms of functionality, than Windows
    2. Windows is cheap enough that I do not mind spending the money on it. For the $100 that I spent for Vista 64 Home Premium OEM, it is quite worthwhile even if I only use it for 3 years. Yes, there are more apps out of the box for Linux, but it's usually easy to find freeware for Windows with the same functionality. Even Office is now pretty affordable with the Home & Office version.
    3. Games - Wine just doesn't cut it. When I want to play a new game, I want buy it and play it immediately! I do not want to have to do research to see whether some game would work on Wine even before I buy it. I do not want to spend hours troubleshooting on the internet if something doesn't work right.
    4. There's always something that you want to change in Linux that you can't figure out. Yes, usually the solution is on the internet. And I used to even enjoy spending time and looking for the solution. But, it eventually grew old. Now I just want things to work and keep working.

    Note that I do love Linux and actually have a server that doubles as a mythtv HTPC setup. It's a beautiful thing. I am comfortable with shell commands and frequently use SSH to perform multiple functions remotely. My opinions above is purely based on desktop usage.

    Great article, Ryan! Putting out some well written Linux articles really adds depth to your site. I have been reading this site daily for years and this article is prompting my first post.

    For future articles it would be great to see some Linux benchmarks in most of the hardware reviews. There are some excellent tools out there (check out http://www.phoronix-test-suite.com/)">http://www.phoronix-test-suite.com/). This would also give some closer apples-to-apples comparisons for Mac vs. Linux performance. I for one would LOVE to see SSD articles report some Linux (and Opensolaris/ZFS) benchmarks along with all the Windows tests.

    Users often don't realize how much they benefit daily from open source software. I don't think most Mac users realize all the OSX pieces that are used in the background for which Apple leverages open source code (Samba for SMB access and sharing, Webkit for Safari, etc.). Home NAS and enterprise storage which serve files in Windows environments are often *nix based.

    It is also a myth that open source means that developers aren't paid. Most enterprises recognize that implementing even commercial apps can require considerable internal development manpower. If enterprise developers can utilize open source code internally and contribute back to the code base, the companies save considerable money and benefit from a healthy software development ecosystem. There are thousands if not millions of developers employed to work on open source code.

    Please keep up the good work. I am looking for your next article.

    Unfortunately the Phoronix Test Suite doesn't work under Windows, so it's of limited utility. It's something we may be able to work in to hardware reviews, but it's not really applicable to OS reviews.

    what i'd like to see on the next ubuntu version is more softer and smoother graphic and font rendering. i hate the way gnome renders the graphic and font. they look old operating system. using the ms core font some how helps but not much.

    i know there's compiz and friends, but i just wish it comes by default, so no need to hassle with compiz and its setting. i wish it could be rendered softer and smoother such as in windows and mac osx.

    the look and feel should be tweaked more often! :D
