Well I have done the upgrade on one VPS. Preparation including backing up
all db and /etc/ plus one or two other "just in case" files and
uninstalling packages that were never installed from official archives 3 or
4 hours, upgrade itself few minutes, sorting out problems all the rest of
the morning.
Problems encountered:-
Bind. Over several upgrades I have always kept the old config files. It
seems that some ancient deprecated options now throw an error not a
warning. systemctl start followed by journalctl -xe details all the
problems, even the line numbers in the files so it was a matter of minutes
to fix
Wireguard still seems to need the unstable repository, so changing that
back it all worked, the conf file was still there so OK, same could not be
said of NFTables, had to reload conf file from back up.
Then the 3 bigger ones:-
Roundcube. During install it said it had to reconfigure the database. I
will have to purge, drop that database and reinstall from scratch
unfortunately
Dovecot. My initial setting up, a few years back took ages (I was learning
as I went) so I said no to replacing conf files. Had same problem as with
Bind, setting which before led to a warning, now stop it from starting.
Same trick as before and only one setting to change. The error message even
tells you what to change it to. I should have heeded the warnings before.
But it does mean that although Dovecot is delivering the mail to the boxes,
I am unable to log onto Postfix as it uses Dovecot to verify credentials.
But then my webmail uses Roundcube so I can't get at that mail at the
moment anyway
Webmin. I use this as a graphical interface when working with big databases
or updating and cleaning up all my zonefiles. It's just easier. Handy for
editing Apache virtual host files. I was able to install it and start it
then the connection drops to the miniserv server. I think it is related to
an upgrading of the perl libraries in the upgrade. Did not have the same
with my home boxes a couple of weeks ago. That is non urgent though.
Hopefully some lessons learnt so mistakes won't be repeated during upgrade
of my other VPS tomorrow. Most of these irritations would probably not have
arisen if I had cleaned up the conf files beforehand.
Hope there is something useful there for anyone else upgrading
