That's not an error.

That's the expected behavior when you miss the release-upgrade window. You are several months too late for a release-upgrade.

  • Your remaining supported release-upgrade method is to backup your data and clean-install a supported release of Ubuntu.

  • There are several unsupported methods you could try...but if you run into problems we won't offer useful help. They are not supported.

  • Consider marking your calendar so you don't miss the three-month-long release-upgrade windows (October-January and April-July). Or consider migrating to an LTS so release upgrades happen every two years.
