Comment 0 for bug 1477455

What happens:

Default installations regularly fail package updates when /boot fills up. While the ultimate cause of this bug lies elsewhere, update-manager gives the user incorrect instructions when the failure occurs:

"Not enough free disk space The upgrade needs a total of 104 M free space on disk '/boot'. Please free at least an additional 85.6 M of disk space on '/boot'. Empty your trash and remove temporary packages of former installations using 'sudo apt-get clean'."

These instructions do not work, and software updates from this point on fail. The user is left vulnerable, unless they have knowledgeable assistance or are technically capable enough to research and fix the problem themselves.

What should happen:

update-manager should provide valid instructions for dealing with this well known problem, or better yet perform the operation itself. It is responsible for keeping the users machine up to date, and needs to handle this and similar failures.
