> Any clue on where I should start looking? Look into reports of problems with your specific firmware for your specific device. See if an update is available. See if there are options in the BIOS menu that control whether these variables are locked. What is the output of 'efibootmgr -v' on this system? If Ubuntu can't control the boot variables, then it can't reliably boot on the system; so the package install failure is intentional. However you also mention that this started happening to you on upgrade and there has been a change in grub's implementation between 18.04 and 19.10, where previously grub shelled out to efibootmgr and now it writes the variables directly. So it's possible there is a bug in the grub implementation. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1851955 Title: ubuntu 19.10 boot installer failed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim-signed/+bug/1851955/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
