Software Updater does not guide user to remove old kernels when /boot
is about to get full, causing failed updates
Status in update-manager package in Ubuntu:
Description: Ubuntu 14.04.2 LTS
*** 1:0.196.13 0
500 http://us.archive.ubuntu.com/ubuntu/ trusty-updates/main amd64 Packages

After running Trusty for about a year, I had easily 3GB worth of old
kernels sitting in my /boot folder.
For users that don't know about pruning old kernel versions, much less
what kernels are, this is a problem since update-manager refuses to
continue the update process when /boot doesn't have enough space.
My friend who I had installed Ubuntu for was complaining about updates
not working, so I took a look and this is what was happening. His
/boot partition is too small to have so many ~200mb kernel images.
We need a user-friendly way to inform the user that this is happening,
and then suggest an automated course of action (apt-get remove oldest
kernel + ensure at least one previous verified working kernel (such as
purge_old_kernels in https://launchpad.net/ubuntu/+source/bikeshed)),
and if it fails, a link to detailed instructions on how to remove old
Attachment is updated ~/update-manager-0.196.13/UpdateManager/Core/utils.py that includes function ensure_enough_room_for_kernel() that only informs the user if there isn't enough space for a kernel upgrade.
It has not been implemented in _main_, I figure the main package devs would want to do that themselves, be it to use for removing the oldest kernel version, or having the user pick from a list of installed kernels which to remove.
