Run into the same problem upgrading 23.10 to 24.04. I run do-release-upgrade. Checking /var/log/dist-upgrade/main.log, I could see that the problem was:
2024-06-14 21:00:38,539 DEBUG Searching for replacement for libts0 2024-06-14 21:00:38,562 ERROR not handled exception: ... File "/tmp/ubuntu-release-upgrader-t3r65jm_/DistUpgrade/DistUpgradeQuirks.py", line 1845, in _install_t64_replacement_packages if replacement.candidate._cand != ver: ^^^^^^^^^^^^^^^^^^^^^^^^^^^ AttributeError: 'NoneType' object has no attribute '_cand' Replaced libts0:1.22.1 with libts0t64 1.22.1-1build1 instead of removing it, and this allowed me to proceed with the upgrade. It hasn't completed yet, I don't know whether I'll find something else. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2067071 Title: cannot upgrade from 23.10 to 24.04, error in _install_t64_replacement_packages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/2067071/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
