Error Prosody under Ubuntu 20.04

Hello,
I have upgraded an Ubuntu 18.04 on which Jitsi work fine to a 20.04. Jitsi was not working so i removed everything and reinstall all.
Now Prosody doesn’t listen port 5347.
I tried to copy the configuration from the 18.04 and the Prosody listen the port 5347.
The result of the command : diff prosody-new/prosody.cfg.lua prosody-old/prosody.cfg.lua is
`33,35c33

< pidfile = “/run/prosody/prosody.pid”;


pidfile = “/var/run/prosody/prosody.pid”;`
I thought plugin_paths = { “/usr/local/lib/prosody/modules” } but it’s in the new file.
What’s going wrong ?

As in ?

# apt-get --purge remove jitsi-meet jitsi-meet-web-config jitsi-meet-prosody jitsi-meet-web jicofo jitsi-videobridge prosody
or
# apt purge jigasi jitsi-meet jitsi-meet-web-config jitsi-meet-prosody jitsi-meet-turnserver jitsi-meet-web jicofo jitsi-videobridge2

# rm -rf /etc/jitsi

# apt-get install jitsi-meet

Prosody not listening on port 5347 is ok. We switched away from component connections to proxy client connections for Jicofo. This is already handled by our Debian packages.

Hello,
apt purge
and then :
find / | grep nginx | xargs rm -rf
find / | grep prosody | xargs rm -rf
find / | grep jitsi | xargs rm -rf
find / | grep jicofo | xargs rm -rf

Hello Saghul,
thanks for your answer.
