Public bug reported: The installer for Ubuntu Server 20.04.4 has no ability to designate an existing EFI system paretition as the boot partition.
The volume is already partitioned and has a valid 512MB EFI system partition formatted as FAT32 and with type code ef00 at /dev/sda1. The installer states that if this partition is selected as the boot partition, GRUB will be installed there. Unfortunately, the option to mount /boot is greyed out. Compounding the magnitude of the failure is that no means exists or is documented to mount boot in this partition. Obviously, the partition can't be deleted to accommodate this failure. Expected behavior: The installer would recognize an existing formatted EFI system partition with type code ef00 as the boot partition without further configuration. The installer would go beyond saying what would happen if such a partition was designated the boot partition, to actually providing a means to make that designation, if the installer wasn't up to the task. What happened instead: Nothing. No progress is possible because the installer can't accommodate an existing partition scheme. ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1966621 Title: Ubuntu Server 20.04.04 installer can't designate boot partition To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1966621/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
