64-bit GRUB refuses to Install

[Jacky Alciné]

On an attempt to install Saucy from 13.04 (Kubuntu), an error occurs in /usr/bin/ucfq on line 529. Initially, I fixed it by editing the file to directly call `Cwd::abs_path` and let the application continue. It didn't solve the problem (and I've redacted such changes).

The error from /usr/bin/ucfq was:

Undefined subroutine &conffile::abs_path called at /usr/bin/ucfq line 529, <HASH> line 21.

The upgrade to Saucy was done using the executable `kubuntu-devel-release-upgrade`.

I've attached a ppa.tar.gz

Updated with the output from the post-installation script first time around; I don't get that issue after reinstalling grub-common.

This is my list of PPAs.

After a bit of tinkering, I was able to notice the following:

On line 380 of the post-installation script for `grub-efi-amd64`, it executes the following:
package="$(ucfq --with-colons /etc/default/grub | cut -d : -f 2)"

However, on line 529 of /usr/bin/ucfq, the following line results in a Perl missing subroutine error:
$self->{Name} = abs_path( $self->{Name});

I changed `abs_path` to `Cwd::abs_path` and the syntax error was gone (it was attempting to pull it from the current object's method list, which isn't the intended behavior).

Glancing at the command again in the postinst script, I changed the field argument in the `cut` command from 2 to 1 and got a path; the one presumably the postinst script was looking for.

Executing the postinst again and it exiting successfully was a good sign. Running 'update-grub' afterwards confirmed my suspicions of a working EFI boot.

OK, I think your ucfq bug is debian bug 711055:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=711055

there is a 3.0027+nmu1 ucf in saucy-proposed that seems to have the fix for that.

[Jacky Alciné (jackyalcine)]

My /etc/default/grub configuration.

[Dave Gilbert (ubuntu-treblig)]

Added ucf as triaged/high, although it seems to be fixed in a -proposed ucf 3.0027+nmu1 (I don't see an Ubuntu bug for that?)

As for the grub cut field, I think the field is right, but with ucf giving junk out previously I think that was upsetting it.

This release of Ubuntu is no longer receiving maintenance updates. If this is still an issue on a maintained version of Ubuntu please let us know.

This issue has sat incomplete for more than 60 days now. I'm going to close it as invalid. Please feel free re-open if this is still an issue for you. Thank you.
