Comment 23 for bug 1183692

Still happening. I noticed that running apt-get autoremove usually clears up enough old kernel versions to fix this, but it didn't work this time.

Surely the updater can be configured to run autoremove and prompt the user yes/no before attempting to install updates? That may fix the issue in a large number of cases; then it would just be a matter of figuring out what is marking some kernel versions as still in use so they're not caught by autoremove.

Also, a larger /boot would still be a good idea.
