Karl, Paul, doing some comparisons of /etc/init.d startup scripts
between my latest backup of 18.04 an what's in the same folder of 20.04
I found that the bind9 startup script was missing although there was
one called named. I had tried earlier to stop the currently running
process with no luck it seemed which is why I kept getting the error of
the something else listening on port 53. After I used sudo kill -9
named the process went away and I had copied the bind9 startup script
from my backup over to /etc/init.d. Once I ran sudo /etc/init.d/bind9
start all is well. I've been running bind9 since 14.04 and never had
any issues, it was suggested way back on the Spamassassin list that I
use it due to extended query times. I've also found a few other issues
such as:

2. All Spamassassin rules in /etc/spamassassin missing.
3. All Spamassassin rules in
/var/lib/spamassassin/3.004004/updates_spamassassin_org missing
4. Updates_spamassassin_org.cf missing in
/var/lib/spamassassin/3.004004/updates_spamassassin_org missing

I may find more as the day goes on but for now I've got internet back
which solves a lot of problems.

Thanks Colin, Liam, Chris, Karl and Paul (hope I didn't miss anyone who
gave suggestions) for the valuable assistance.

Chris
