Upgrade Ubuntu 20.10 to 21.04

pl flag

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:
    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).

These types of upgrades can be dangerous, Thus are not recommend , Your ubuntu version 20.10 is no longer supported by canonical Thus cant be upgraded _safely_ , the method you _can_ try to do this upgrade is editing `sources.list` but this method can be dangerous!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
