Public bug reported: So I'm trying to upgrade my storage machine (which I also use as a remote desktop) from 18.04 to 20.04 and the upgrader is failing.
/var/log/dist-upgrade mentions 2020-10-31 12:25:37,733 INFO installing python-is-python2 because python-minimal was installed 2020-10-31 12:25:37,733 DEBUG Installing 'python-is-python2' (python-minimal was installed on the system) 2020-10-31 12:25:37,981 ERROR Dist-upgrade failed: 'E:Unable to correct problems, you have held broken packages.' There aren't any held/broken packages. It seems a similar issue to this (with the mention of python-is-python2) https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1875523 but the upgrader is already on 20.04.28 I did have this ppa installed for some reason ppa:ubuntu- toolchain-r/test but removed that as one of the first troubleshooting steps (and then had to copy a lib file from another machine to fix apt...). But basically, is it something I've done or is it the upgrader?
