ubuntu upgrade to 22.04 has lost port 80 for http access

[bgra...@umw.edu]

Hello,

I have been running ubuntu 20.04 with the latest weewx for quite a while and no problems with port 80 for local access. The upgrade seemed to go well for everything but apache2 which would not restart. A port scan shows no port 80 is open. Everything else restarted fine (as far as I know). My weewx server FTPs to my web site (grattans.org/wx) and seems to be running ok on the upgraded server. I'm not a programmer and not sure how to interpret some of the error messages. Here are some observations:

- Port #22 (ssh):  listening
- Port #25 (smtp):  listening
- Port #139 (netbios-ssn):  listening
- Port #445 (microsoft-ds):  listening
- Port #3389 (rdp):  listening
- Port #9418 (git):  listening
- Port #10000 (webmin):  listening

Obviously you have an error in one of your apache config files, but you didn't provide the full transcript to show which file line 3 it is referencing is for.  I would guess (wild guess) that you're trying to load a file that you didn't actually install in your ubuntu setup.   There are a lot of little dpkgs to use.

(which is another reason I use nginx, it's nice and simple)
