Comment 31 for bug 104337

-----Begin Error message-------
Not enough free disk space

The upgrade aborts now. The upgrade needs a total of 41.9M free space on disk '/boot'. Please free at least an additional 18.8M of disk space on '/boot'. Empty your trash and remove temporary packages of former installations using 'sudo apt-get clean'.

I was about to file a bug, but will request for a feature now. Wouldn't it be nice
1). to have a warning during the initial installation of Ubuntu, that suggests one to choose the size of the partition for /boot (if it is separate) to be not less then **M;
2). to suggest one to delete old kernel packages using a _package_manager_?

I've lost more then an hour on this issue...
