[Bug 1201112] Re: 64-bit GRUB refuses to Install

[Jacky Alciné]

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.

Title:
  64-bit GRUB refuses to Install

Status in “grub2” package in Ubuntu:
  New

Bug description:
  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:

  529, <HASH> line 21.

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

  I've attached a ppa.tar.gz
