Go to terminal, either an app or via Ctrl-Alt-F2.

Become a real user:

sudo su -

unless you like this 'sudo' litany.

Find offending processes and kill them all.

Then

apt-get update
apt-get upgrade
apt-get dist-upgrade

If any of those fail, run

apt-get -f install

and repeat 'upgrade' and 'dist-upgrade'

You can also do

apt-get --purge remove snapd unattended-upgrades

at any time

Check, that you still have some kernels to boot:

update-grub

and reboot.
