I do not understand why people do not simply, when performing system 
updates/upgrades, apply the sequence repeatedly previously mentioned on 
the mailing list;

apt update
apt full upgrade -y
apt autoremove
apt autoclean

It is simple an effective, and, it takes care of redundant kernel images 
and associated packages, and other superseded and otherwise redundant 
packages.

I preface the set of four commands, with
sudo -i
which acts like the (non-Ubuntu) command
su -root
and I follow the four commands with
exit, so as to avoid inadvertently abusing the superuser mode to 
inadvertently cause system level problems.
