> I think it would be resolved by updating this file in the ubuntu server, with adding an entry for 20.04:
That is not a solution to this bug. Upgrades have INTENTIONALLY not yet been turned on by default from 18.04 to 20.04; we do this only after the first point release of an LTS. If you are running do-release-upgrade without the '-d' option, it is the expected behavior that you are not offered the upgrade. If you are running do-release-upgrade /with/ the '-d' option, please provide the debugging information requested in comment #5. I have updated the bug title to make it clear that this is about the behavior with -d. ** Summary changed: - do-release-upgrade does not work to upgrade to 20.04 LTS + do-release-upgrade -d does not work to upgrade to 20.04 LTS -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876420 Title: do-release-upgrade -d does not work to upgrade to 20.04 LTS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1876420/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
