I've found the problem. I run Bind9 as a caching name server and for
some unknown reason it's not starting since the upgrade:

localhost named[290337]: using default UDP/IPv4 port range: [32768,
60999]
localhost named[290337]: listening on IPv4 interface lo, 127.0.0.1#53
localhost named[290337]: creating TCP socket: address in use
localhost named[290337]: unable to listen on any configured interfaces
localhost named[290337]: loading configuration: failure
localhost named[290337]: exiting (due to fatal error)
localhost systemd[1]: bind9.service: Main process exited, code=exited,
status=1/FAILURE
localhost systemd[1]: bind9.service: Failed with result 'exit-code'.

I 'think' if I can get that figured out I may be on the way to getting
this back up again.
