Software Updater freezes when trying to upgrade grub-pc package
Status in ubuntu-release-upgrader package in Ubuntu:
Ubuntu version: 14.04.2
When running Software Updater (update-manager) to update the packages,
it freezes when trying to update grub-pc package.
I think this is related to the fact that grub-pc detected a
modification of a configuration file and needs to ask the user for
confirmation on the action to take. However, the package required to
display this (libgtk2-perl) is not installed by default.
Steps to reproduce the problem:
1 - install a fresh stock version of Ubuntu 14.04.2 on your device
2 - modify the file /etd/default/grub (for instance, comment the line "GRUB_HIDDEN_TIMEOUT=0" or simply add a comment at the end of the file), then save and run `sudo update-grub2`
3 - Restart the computer and start "Software Updater"
Updates are being downloaded and installed. However when reaching grub-pc configuration, the window turns black and white and it has to be killed. (see attached screenshot update-manager-freeze.png)
In order to fix the problem, before running the Software Updater, you
need to install package `libgtk2-perl`. In that case, a new window
will be displayed to ask what to do with the modified configuration
file (see screenshot grub-gui-choice.png).
Note that this problem does not happen when running the update through
a terminal (sudo apt-get update && sudo apt-get dist-upgrade) because
the grub modification confirmation is then displayed using ncurse.
