"sudo apt-get autoremove --purge"

This will remove all old kernels except for the current and the previous current, as well as any other old unnecessary
packages.  It removes them and all their related files so you get the disk space back.

I run that command after every dist-upgrade that installs a new kernel (which on the -dev version of Ubuntu is about
once a week).  I have never run into trouble.
