Last one (I think): where is the Nginx parameter set for the SSL certificate?

[Keith_Rettig]

Nginx is failing on start up. Complains that the SSL cert for the admin user or main domain is missing. But the domain it is trying is from when I was testing and the production domain is different.
Let it be known that the user-data folder was copied over from an existing MiaB where the server seems to be failing (it is going very very slow).

FAILED: service nginx restart

Job for nginx.service failed because the control process exited with error code.
See “systemctl status nginx.service” and “journalctl -xeu nginx.service” for details.

I looked and googled a whole lot and I can’t find where this parameter is being set. It needs to be refreshed to the correct value. All the correct SSL certs are in the directory specified where it can not find the SSL cert with which it is incorrectly looking.

sudo nginx -s reload [doesn’t work unfortunately]

Searched for another hour or so and found that the issue was this file;
/etc/nginx/conf.d*/local.conf

It had the list of all the domains from the previous set up. I copied the file from the misbehaving server. Got past the Nginx part of the install but then failed at

Installing Munin (system monitoring)…

E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?

I give up. Going to start over and reinstall Ubuntu 22.04 from scratch. Will take me less than an hour…
