When the new Ubuntu version comes out on April 21, I am looking forward to update. However, many of the sources in my software list (e.g. wine, lutris, other general ppa sources) are set to impish. When I update to Jammy via software updater, will the sources be updated, or will I need to manually set them to Jammy?

  • Official Ubuntu repositories are changed to reflect the new release; but 3rd party software sources are disabled. Third party packages can prevent upgrade, so some may need to be removed (eg. Oibaf graphics drivers often prevent release-upgrade from occurring, and need to be ppa-purge removed before upgrade can occur). – guiverc Mar 06 '22 at 05:54
  • Ubuntu 22.04 doesn't yet exist; it's currently the development release Ubuntu jammy and remains that until it reaches RC state which isn't expected until after 14 April 2022, and isn't on-topic here until release on 21 April 2022. https://discourse.ubuntu.com/t/jammy-jellyfish-release-schedule/23906 Please refer https://askubuntu.com/help/on-topic. For support issues with Ubuntu jammy you'll need to use a #ubuntu-next or #ubuntu+1 site (IRC, UF etc) – guiverc Mar 06 '22 at 05:54

During ANY release-upgrade:

  • Ubuntu deb sources WILL be automatically changed (renamed) to the new release.
  • PPA sources will be automatically disabled, not changed. Many PPA sources are not ready on release day, so disabling the sources prevents "source not found" errors. Best practice is to review PPAs at release-upgrade time anyway: Many PPAs may be superseded by versions from another source.
  • Non-Ubuntu deb sources (including wine and lutris) WON'T be changed. Like PPAs, review each source at release-upgrade time to see if you really still need that source.
  • Snaps should be unaffected, since their updates are not related to the release of Ubuntu.

Keep in mind that PPAs and non-Ubuntu sources are generally not well tested by volunteers when preparing releases of Ubuntu -- more volunteers to do that testing are welcome! It's moderately common for PPA and non-Ubuntu software to block release-upgrades or cause partial upgrades (those are bad).

Best practices during any release-upgrade to have the highest likelihood of success is:

  1. Backup your data before starting.
  2. Return your Ubuntu system to as close to stock condition as possible. That means uninstalling all software from PPAs and non-Ubuntu deb sources. You don't need to uninstall packages from the Ubuntu repositories. You don't need to uninstall snaps.
  3. Do the release-upgrade.
  4. Review your PPAs and non-Ubuntu sources. You might want to start using software that is now available in the Ubuntu repositories or via snap instead. Check that PPAs have a version for the new release. Check that non-Ubuntu sources have been tested with the new release.
  5. Reinstall PPA and non-Ubuntu software one source at a time, testing before moving to the next software.
