Lubuntu 18.04 LTS End of Life (30-April-2021)

Further to the recent warning post the end of life of Lubuntu 18.04 LTS is upon us.

Official notice is as always found on our blog,

Lubuntu 18.04 (Bionic Beaver) was released April 27, 2018 and will reach End of Life on Friday, April 30, 2021. This means that after that date there will be no further security updates or bugfixes released. We highly recommend that you re-install with 20.04 as soon as possible if you are still running 18.04.

After April 30th, the only supported releases of Lubuntu will be 20.04 (until April 2023), 20.10 (until July 2021), and 21.04 (until January 2022). All other releases of Lubuntu will be considered unsupported, and will no longer receive any further updates (or support) from the Lubuntu team.

You can find instructions on how to install Lubuntu in our manual.

Note, due to the extensive changes required for the shift in desktop environments, the Lubuntu team does not support upgrading from 18.04 or below to any greater release. Doing so will result in a broken system. If you are on 18.04 or below and would like to upgrade, please do a fresh install. The installation image can be obtained from our downloads page.

For further details please refer to our forum post.

Please note: in the coming days, you may find Lubuntu pages on will be moved (and if you access them via saved URLs, even search engines which rely on prior searches, you’ll get errors). Lubuntu will be LXQt only going forward, so a wiki clean up task was created which I’ll action in a few days.


Farewell, LXDE. It was good to know you.

/me pours one out for his homie


Cheers to you mate. Incredible how far things have come along.


Please note:

If you architecture is i686 or x86 (32-bit) (what Debian & Ubuntu both refer to as i386) then Lubuntu 18.04 LTS was the end-of-road for Lubuntu.

Later Releases (18.10 & 19.04)

Yes we released Lubuntu 18.10 with the modern LXQt desktop. Lubuntu even produced alpha ISOs into the disco (19.04) cycle, which if installed, package updates were provided until 19.04 reached EOL (though Lubuntu never officially supported disco/19.04 in i386), however both 18.10 & 19.04 reached EOL long ago meaning Lubuntu 18.04 LTS was the last i386 system supported.

Can I continue using it ?

Yes you could, I’d suggest fully exploring your support status using ubuntu-support-status. Packages found in the ‘main’ repository will still get security updates, where you’ll note firefox still get security updates :slight_smile: even if your desktop & many apps are now unsupported.

The risk is your decision, however if you have questions (understanding ubuntu-support-status or other), you can ask and I’ll give my thoughts/opinion in most cases.

What are my alternatives ?

There are a few; myself I also test (and love) Debian so it’s all I’ll suggest. I tested Debian 10/Buster on my i386 hardware, and performance was on most boxes very similar (on my lowest powered box Lubuntu 18.04 well outperformed Xubuntu or Debian 10/Buster but on most hardware the performance difference was very small).

Debian 10/Buster has more of it’s life left than Lubuntu 18.04 LTS so it would be my main alternative if you’re forced to use a i386 box.

(I still use i386 boxes; but almost all my online tasks are performed on much more modern amd64 hardware)
