Hello,

I'm trying to do the recent upgrade of Ubuntu, but the update is stuck and I get this error message:

 E: The repository http://archive.canonical.com/ubuntu lunar Release does not have a Release file.

I'm really not an expert, so if someone could help me and explain how to get this file, that would be great.

    Hello,

    As far as I can see here, at the time I'm writing this, the "lunar" release does not exist for the repository http://archive.canonical.com/. The APT configuration is therefore inconsistent and it's not surprising that your package manager is confused.

    To fix the issue, remove from the /etc/apt/sources.list file (or one of the files in /etc/apt/sources.list.d) the corresponding line, or comment it out by adding a # at the beginning of the line:

    sudo gedit /etc/apt/sources.list &

    If you're unsure about the concerned line, please let us know its content.

    Once that's done, save, exit, and then run:

    sudo apt update sudo apt upgrade

    Good luck

    Hey

    Public versions:

    On ccm you can find this ubuntu 64 bits 20.04 LTS download

    https://www.commentcamarche.net/telecharger/systemes-d-exploitation/25121-ubuntu/

    A filename that might look like this is lunar lobster but not from canonical the file and it's not an LTS

    https://cloud-images.ubuntu.com/releases/23.04/release-20231205/

    I think the last LTS is from 2022

    https://doc.ubuntu-fr.org/lts

    A help page

    https://lecrabeinfo.net/mettre-a-jour-ubuntu-20-04-lts-vers-22-04-lts.html

    A more general explanation of the versions

    https://www.malekal.com/ubuntu-les-cycles-de-versions-et-de-mise-a-jour-versions-lts-ems/

    And the support from Canonical, it can be paid for companies more generally, there I don't know but generally those who use this are already aware of updates, they don't search everywhere for files.

      A little more:

       -Lunar Lobster tutorial 23.04

      https://doc.ubuntu-fr.org/tutoriel/installation_lunar_23.04

       -Version table with Mantic Minotaur 23.10 that was missing from my list

      https://doc.ubuntu-fr.org/versions

       -And of course, since the Ubuntu wiki page doesn't exist yet, the download for Mantic 23.10

      https://releases.ubuntu.com/mantic/

      *

      Option:

      It was originally for upgrading from Kubuntu 20.04 to 22.04, but it's Ubuntu, and there are commands that Linux users use, and it's a migration by mamiemando on CCM:
