Code:

insserv: FATAL: service dnsmasq is missed in the runlevels 2 3 4 5 to use service apache2

That's causing the error.

Could you try

A) set package dnsmasq and apache2 on hold before running upgrade
sudo apt-mark hold apache2 && sudo apt-mark hold dnsmasq and try again

or

B) temporarly deinstall both packages, run the upgrade and reinstall them after upgrade has been done

Both options did not work out; in the end I am still ending up in the same error.
I checked in option B if dnsmasq or apache2 were still running or installed, but that was not the case.
So I don't understand that insserv is still checking upon apache2 and dnsmasq
I will call it a day for now and dig into it the day after tomorrow...
