Fast forwarding eight months, this still breaks a fully-updated xubuntu LTS 16 to LTS 18 release upgrade, at least. Does this need to be pushed to LTS 16 (or 18 if the new package is run)?
Mounting the disks on the host (error was in a VM guest), chrooting, and running grub-install /dev/sda fixes, so this doesn't seem like a complex disk layout issue. I'm about to see if fully-updated LTS 18 to LTS 20 also breaks ... yep 'grub_file_filters' is the symbol this time. Same fix. Is it correct that do-release-upgrade has been broken in this way for most of the past year? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1889556 Title: grub-install failure does not fail package upgrade (and does not roll back to matching modules) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1889556/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
