There were two issues: (1) mesa in focal has lower version than in releases, newer one stuck in proposed
(2) ubuntu-release-upgrader did not check that the solution it picked at the end (after re-marking meta packages for upgrades) was actually valid. It assumed that if mark_upgrade() failed, the operation was a no- change, when it actually led to broken packages. (2) is fixed, (1) should be fixed soon. ** Also affects: mesa (Ubuntu) Importance: Undecided Status: New ** Changed in: mesa (Ubuntu) Status: New => Fix Committed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1861756 Title: upgrade from 18.04 to 20.04 issues due to colord / libsane issue To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1861756/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
