Hello,
I am trying to reinstall jitsi-meet on a Debian 10 system using apache2. The first time I had followed the video tutorial and it was very smooth. The installation worked, but it was for a made-up local domain with a snake-oil cert. I then decided to redo it with a true domain and cert. I got a Letsencrypt cert and got https working fine with an empty site, without using jitsy procedures.
I gave the apt-get purge command seen in the quick install guide to remove the first installation. The system could not purge jigasi due to a user name does not exist error (I tried repeating the command as suggested but the error stayed). I continued anyway with apt autoremove and apt -y install jitsi-meet.
At this point it asks me for the hostname, and then it gives me a choice between generating a self-signed certificate or using my own, and I choose the second. Then it asks me for the keys and cert paths. Here I indicate the letsencrypt locations /etc/letsencrypt/live/<host>/{privkey.pem,fullchain.pem}. Then the installer concludes after writing out a note that I need to run /usr/share/jitsi-meet/scripts/install-letsencrypt-cert.sh .
But this is puzzling, since this procedure seems to run cerbot again and prompts me with the email for the ACME agreement - I already went through this and I already have the cert installed and tested, and I can use https without problems.
What is the proper way to do a reinstall with an existing valid Letsencrypt cert? I made another test after putting symbolic links in /etc/ssl pointing to the Letsencrypy key and cert, but it did not seem to help.
Thanks
