Public bug reported: There are still a lot of bug reports where users cannot upgrade from Ubuntu 18.04 LTS to Ubuntu 20.40 LTS due to python still being kept when the problem resolver runs. This is due to a bit of code being removed when 20.04.31 was uploaded. That code should be restored as it will allow more users to upgrade to Ubuntu 20.04 LTS.
[Test Cases] 1) lxc launch ubuntu:18.04 2) Restore the apt-clone file from LP: #1927268 3) Run do-release-upgrade 4) Observe a failure to calculate the upgrade to Focal With the version of the release upgrader from -proposed (do-release- upgrade -p) the upgrade to Focal will be calculated successfully. [Where Problems Could Occur] This code previously existed in the release upgrader and just ensures that we are are moving python from the system. However, there could also be typos in the restored code but that would cause a Traceback when running the test case so that would get caught.  http://launchpadlibrarian.net/531097604/ubuntu-release-upgrader_1%3A20.04.30_1%3A20.04.31.diff.gz ** Affects: ubuntu-release-upgrader (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1928397 Title: ensure python is marked for removal when upgrading from 18.04 to 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1928397/+subscriptions -- ubuntu-bugs mailing list email@example.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
