I have a PC with a Lubuntu Groovy 20.10. Now I want to reactivate this PC. The lifetime of the distribution has expired. Any try to update software fails. It was not a LTS version, so it happened. I'm out.

Is the only way to a current version a backup all files in the personal directories, get a list of installed software and perform a complete new installation?

How can I update to recent version, preferable a LTS version?

Edit I got the hint to read This question. It looks like to give a great answer. But the command

sudo apt-get update && sudo apt-get dist-upgrade

fails with the error:

$ sudo apt-get update && sudo apt-get dist-upgrade

roughly translated as

N: An update from such a repository can't be performed in a secure way, it's therefore deactivated.

The error messages come from sudo apt-get update. Is there anything I missed?

    Does this answer your question? How to install software or upgrade from an old unsupported release? – nobody Mar 05 '23 at 12:24

    It maybe easier to backup your data and install a current version. The 404 error may be a temporary outage. Try again later. – user68186 Mar 05 '23 at 13:31

  • I'll suggest you read my answer in the duplicate I marked.. I mention "one flavor in particular" which is actually Lubuntu. The install I'm suggesting is called "Install using existing partition" in Lubuntu (our 22.04.2 QA checklist can be seen here and you can read https://discourse.lubuntu.me/t/testing-checklist-understanding-the-testcases/2743 to help understand it; that doc is intended for QA-testers (not end-users) but I'd expect still helpful.... or answer I suggested on this site via duplicate – guiverc Mar 05 '23 at 22:06
  • Your sources are incorrectly the release is/was groovy and not groovy-old-releases. Use an LTS release in future; as 20.10 was the first release on the two year development road towards 22.04, with the supported upgrade to the next release (ie. 20.10 -> 21.04 -> 21.10 -> 22.04). Upgrades to 22.04 are available from the prior LTS (20.04) or from the end of the current cycle (21.10); you can jump from 20.04 to 20.10/21.04/21.10 then all releases but not early-mid-cycle to end-cycle as you are attempting... Did you read the changes in release notes too? – guiverc Mar 05 '23 at 22:10
  • Also backup any data you value... as installs of any type can destroy data, and the re-install I mention requires you to correctly select for re-use your existing partition(s) & ensure you don't format... If you format you'll get a clean system without data; it's the lack of format (on existing partitions) which triggers this repair type installation. – guiverc Mar 05 '23 at 22:13
  • Since the sources are incorrectly configured even if I restore the previously save configuration file, I decided that my system is not able to be upgraded. I deleted Lubuntu, installed Lubuntu Jammy LTS 22.04 and restored my home directory backup. Now I setup a fresh set of applications. – harper Mar 09 '23 at 07:28
  • Given you restored your home directory from the older release, check you didn't restore the openbox settings from groovy (20.10) as per https://lubuntu.me/jammy-1-released/ (See the Upgrading Lubuntu to 22.04 LTS section as you will most likely have overwritten the 22.04 setup) FYI: A re-install without format would have also re-installed your previously manually installed applications too; instead of you needing to install them manually. – guiverc Mar 09 '23 at 07:33
  • The installer failed to install without re-format. There was "not sufficient space". The hard disk was filled with less than 25%, so i can't guess the reason. Well, now get I a new set of programs. Some unused will be wiped not. That is maybe the right way. At least this doesn't cost so much time to frickle with the update way to go. I did not see a chance to fix "Your sources are incorrectly". – harper Mar 09 '23 at 07:58
