I try to upgrade my Ubuntu 20.10 to 21.04.

  1. Using the GUI Software Updater gives following information:

    Software updates is no longer supported for Ubuntu 21.10 To increase security please install Ubuntu 21.04

    So, I follow instruction and click the Upgrade button! The GUI Software Updater just shuts down without response or information.

  2. I tried the release upgrade as below.

    $ sudo do-release-upgrade
[sudo] password for thomas:
Looking for a new Ubuntu release
Your Ubuntu release is no longer supported.
For upgrade information you can visit:
http://www.ubuntu.com/releaseendoflife
Install all available updates for your version before upgrading.*

    As far as I known I have installed all updates from Ubuntu, and the GUI Software & Updates app is configured for daily information for updates. All previous version updates without problem.

So I kindly ask for your help in this issue to upgrade 21.04.

  • Your Ubuntu release is no longer supported says it all. The time for a normal online release upgrade is already gone. There is a way to do it (see next comment) but you have to ask yourself if it's worth the time, effort and risk when compared to (having backups and) doing a fresh 21.10 installation (21.04 will be EoL soon). – ChanganAuto Nov 17 '21 at 10:55
