Please advise

You’re not using a supported release of Ubuntu or Lubuntu.

Please read

Supported releases of Lubuntu are

  • Lubuntu 22.04 LTS (current LTS)
  • Lubuntu 22.10 (old-stable)
  • Lubuntu 23.04 (latest stable release)

Even Ubuntu 18.04 LTS completed it’s standard support; I’d suggest using ubuntu-support-status to check your security status of your actual install. Please see Ubuntu Fridge | Extended Security Maintenance for Ubuntu 18.04 (Bionic Beaver) begins 31 May 2023

i386 is no longer a supported architecture of Ubuntu on any release; the only supported 32-bit architecture now is armhf.

Later edit & Clarification: Ubuntu 18.04 still has extended or ESM support options (including Ubuntu Pro) however they are for specific architectures only and all are 64-bit (amd64, arm64, s390x, ppc64el). armhf (32-bit ARM) support exists still on 20.04 & later releases for Ubuntu.


Hi guiverc

Thank you very much for your informative and sharp response!

Best wishes



I’m sorry, even Lubuntu devs will say this, but the best way to go for your old 32 bit system is:

Debian is like ubuntu, so learning curve is minimal. During install you can select LXQT or LXDE as a desktop and it will just be the same as Lubuntu.


I wrote about i386 here and many other posts. Debian would be my choice; though the release would vary on the hardware (esp. GPU) for me, as I found some of my old hardware performed better on older kernel stacks (thus an old-stable or old-old-stable for some).

i386 is no longer a supported architecture for Ubuntu on any release, with the only 32-bit now being armhf as already stated.
