I am opening this ticket as grub-installer should give a more descriptive error message in case FastBoot is enabled.
It worked after disabling FastBoot (I disabled also SecureBoot as I don't use it but that's irrelevant i guess). Which is the process for such request? Should I register at below link and report it there? http://savannah.gnu.org/bugs/?group=grub ** Summary changed: - grub-installer documentation + grub-installer error message at FastBoot -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1639612 Title: grub-installer error message at FastBoot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1639612/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
