Please improve clean-up instructions / config files affected

[akemper]

Quite a few times I had issues with a clean installation start , after previously triggering the suggested "apt purge ...", including even prosody and coturn packages there. The two most frequent problems during / after subsequent installations were either:

1. Everything seemed to work fine, but in the end couldn't see / hear each other's audio / video, even after completely disabling the firewall and rechecking host names
2. Couldn't change to a new domain name on an existing system

In either cases pretty sure there have been some orphaned config files causing the issues, but my overall Jitsi and Java understanding is too limited to follow-up there with reasonable effort. Thus it would be good to provide some more details on the requirements / dependencies there in the instructions.

as apt purge should remove all regular configuration files:

On the other hand you can get rid of these leftovers by calling
purge even on already removed packages. Note that this does not affect any data or
configuration stored in your home directory.

The problem must be that Jitsi stores configuration files somewhere else.
Thus you are right, it should either be fixed or we need further documentation for a clean uninstallation.
