Ubuntu 15.04 desktop users will receive no more security notices, critical fixes, or updated packages from the main Ubuntu archives as of February 4th, 2016.
The nine-month-old operating system is notable for being the first version of Ubuntu to use Systemd as its default init system, a change brought about to keep the OS in sync with upstream.
The number of affected users who still use this version of Ubuntu is unknown.
While the shuttering of official support doesn’t directly affect third-party software that is distributed through private repos and personal PPAs, many developers are likely to stop providing packages for 15.04 in the coming weeks.
How Long Is Ubuntu Supported For?
Wondering how long each version of Ubuntu is supported for? It’s a fair question.
Since 2013 all non-LTS Ubuntu releases receive updates for 9 months. For LTS (‘Long Term Support’) releases the support cycle is 5 years.
Following Vivid, Ubuntu 15.10 (aka ‘Wily Werewolf’) will be the next version of the OS to hit EOL. Official support for Wily, still the incumbent stable release, wraps up in July, 2016.
Ubuntu 12.04 LTS is set to bow out next April after receiving 5 years of on-going updates,.
Ubuntu 16.04 LTS is due in April of this year and will be supported well into the next decade.
How To Upgrade from Ubuntu 15.04 to 15.10
If you’re still running 15.04 don’t panic: your computer isn’t about to die, explode or sprout facial hair. You can continue to use it as normal for some time yet.
But you should consider upgrading to the most recent stable release, Ubuntu 15.10 ‘Wily Werewolf’, as soon as you’re able to. This will protect you from any future security exploits, nix any critical bugs, and ensure you’re running the latest versions of apps like Firefox and Thunderbird.
Canonical advise users who run out-of-date Ubuntu releases to upgrade using the built-in Software Updater tool.
The recommended upgrade path from Ubuntu 15.04 is to 15.10. This transition can be handled from the desktop using the Software Updater application.
If you’re more comfortable with the command line you can issue the following command to upgrade Ubuntu 15.04 to Ubuntu 15.10 directly:
sudo do-release-upgrade
A Less Than Vivid Release
Ubuntu 15.04 ‘Vivid Vervet’ was released on April 23, 2015.
“Despite the name there were no ‘Vivid’ changes on show…”
Vivd by name, but rather humdrum in nature; Ubuntu 15.04 was a modest release, but notable for a few select reasons:
- First version of Ubuntu to use Systemd as the default Init System.
- Unity 7.3 desktop allowed application menus to be set to ‘Always Show’
- Faster login/logout animations
