Public bug reported:
The problem:
While installing Ubuntu 21.04 on a machine today, I faced grub install failed
errors lot of time.
Later I was able to solve the issue but the error ubiquity was throwing were
every irrelevant and helped me no where in resolving the issue. I was not able
to report the detailed bug report using Apport when i faced this but I will
line out complete reproduction steps below.
How to reproduce:
- Select manual partitioning in install wizard.
- Try to create a EFI partition (When i didn't created a EFI partition the
installer reported there is not enough space left in EFI partition grub-install
failed). Also a user who is using legacy boot don't know why the installer even
need a EFI partition, so they won't create it manually and will end up with
same grub-install failed error.
- The create partition prompt that came up by default chose partition type
Logical for me, even if I chose EFI in filesystem type.(Knowing that the
installer will fail if the EFI partition type is set to logical).
- Process to install Ubuntu.
- A grub-install failed prompt appears while completing the install. (Here when
i looked in the install log, the last error reported was : grub-install : error
failed to register the EFI boot entry:Operation not permitted)
Here how i solved this:
I changed the partition type of EFI volume to Primary from Logical.
What's expected:
If the EFI partition is needed even in the legacy boot mode by the
installer, Ubiquity should let the user know about this before letting
him start the installation. Or by creating one for him by itself instead
of letting them proceed the installation and later present them the grub
install failed dialog (new users don't know what is grub).
When user choose a partition filesystem type to EFI, switch the
partition type from Logical to Primary by default(cause that's what we
need to install grub in it). This only took my 2-3 hours figuring out
where i did go wrong (I don't how a new user will deal with this).
