It looks like it might be Weewx itself that is not launching. Seems maybe 
the Ubuntu Pro did something to prevent Weewx from loading. I am looking 
back into the syslog and I see stuff like this:

Oct 16 09:49:42 weewx-pi systemd[1]: weewx.service: Main process exited, 
code=exited, status=2/INVALIDARGUMENT
Oct 16 09:49:42 weewx-pi systemd[1]: weewx.service: Failed with result 
'exit-code'.

and:

Oct 16 09:50:01 weewx-pi kernel: [   81.929080] audit: type=1400 
audit(1665935401.678:43): apparmor="DENIED" operation="capable" 
profile="/snap/snapd/17029/usr/lib/snapd/snap-confine" pid=796 
comm="snap-confine" capability=12  capname="net_admin"
Oct 16 09:50:01 weewx-pi kernel: [   81.929423] audit: type=1400 
audit(1665935401.678:44): apparmor="DENIED" operation="capable" 
profile="/snap/snapd/17029/usr/lib/snapd/snap-confine" pid=796 
comm="snap-confine" capability=38  capname="perfmon"

Got to try and figure out how to get it to launch; maybe do a reinstall of 
weewx?
