Hi Wayne, Thank you for reporting the issue.
I am able to reproduce it using this URN 'Canonical:UbuntuServer:18.04-LTS:latest'. By checking APT logs, the issue seems related to python2. Indeed, if I remove python2.7 (apt purge python2.7) before doing 'do-release-upgrade', the upgrade goes fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1923111 Title: Azure Ubuntu 18.04.5 LTS hit a bug when running 'do-release-upgrade' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1923111/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
