This is so that, - a specific grub package is installed - a specific grub target is used to boot are separate states.
Then the installer can decide which grub(s) to install, and those will be-reinstalled on package updates. I believe this is by design. You can just run grub-install once by hand, and it will all update correctly afterwards. ** Changed in: grub2 (Ubuntu) Status: New => Opinion -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1879558 Title: grub-efi-amd64 postinst fails to install GRUB if previous GRUB install is not detected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1879558/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
