Wow. I was reading the thread and was starting to think that there
weren't any uninstallable kernels installed.

I've found "purge-old-kernels". It's shipped in the "byobu" package.
It's now (on 21.04)

# apt autoremove supposedly works correctly now.
# Thus, we're deprecating the functionality previously found
# in purge-old-kernels.

sudo apt-get $@ autoremove

You're on 16.04 (EOL in 7 weeks or so), so I guess that "autoremove"
isn't working correctly on it, for kernels.

This is the old version of the script
