The command do-release-upgrade downloads a tarball of ubuntu-release- upgrader from the release to which you are upgrading e.g. http://archive.ubuntu.com/ubuntu/dists/bionic-proposed/main/dist- upgrader-all/current/bionic.tar.gz. That tarball is then extracted into /tmp/ubuntu-release-upgrader-$TEMP/. To confirm you are getting the right version of the tarball you can check DistUpgradeVersion.py in that folder. It should contain 18.04.33. It looks right to me:
bdmurray@clean-xenial-amd64:~$ cd /tmp/ubuntu-release-upgrader-pn4lfyfj/ bdmurray@clean-xenial-amd64:/tmp/ubuntu-release-upgrader-pn4lfyfj$ cat DistUpgradeVersion.py VERSION = '18.04.33' -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1796193 Title: DistUpgradeViewNonInteractive crashes / requires interaction To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1796193/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
