Here is some update. My script does not use linux-version anymore. But I named the script linux-purge. It can remove kernels even in some problem cases where e.g. there are dependency problems due to an unsuccessful kernel update (e.g. due to full /boot partition). It provides optional UI for interactive checklist based kernel removal. It does not support kfreebsd-image and gnumach-image kernels, but only Linux kernels and it is designed to work in any flavor of Ubuntu. Here is a demo that shows it in action: https://youtu.be/TpsZoAnOVTU
I have not published the script yet, but maybe later, if there is enough interest. -- Jarno Suni - http://iki.fi/8/ > On Tuesday, May 24, 2016 2:29 PM, Jarno Suni <j_s...@yahoo.co.uk> wrote: > > Now that linux-base is part of .?ubuntu 16.04, I think it would be good to > > add a > linux-kernel removal tool to linux-base.
