No connections after Debian 9 to 10 upgrade


I had a working Jisti-meet installation on a Debian 9 system.

Since I upgraded to Debian 10 it doesn’t work anymore and I can’t understand why.

The effect is that if I connect from two different PCs I can’t see the respective other connection.

Then also webcam doesn’t show anything, even if it can see it’s working from the “Settings” menu.

From logs I can’t see any “GRAVE” line.

Any idea?


Can you check the java version and make sure default is java8?

Yes, it is:

  Selezione    Percorso                                        Priorità  Stato

* 2            /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java   1081      modalità manuale

As a start maybe check browser logs, do you see any errors there? If that is ok, check prosody and jicofo logs. Check whether your bosh is working by checking its url, should looks like

Thanks, here are browser logs:

It works! Now point your BOSH client to this URL to connect to Prosody.

For more information see [Prosody: Setting up BOSH](

This is suspicious. Check prosody logs for errors, what is the version of prosody you use? What is your prosody config?


I have Prosody 0.11.2-1 and in effect I have these errors in is logs:

Here is missing the jitsi-meet configs, but if you are using prosody-0.11 then make sure you have the following setting for your muc: instead of storage = "null" to be storage = "memory".
Is this like that?

Thanks, I tried, but changing like that seems to have no different effect:

--storage = "sql" -- Default is "internal" (Debian: "sql" requires one of the
-- lua-dbi-sqlite3, lua-dbi-mysql or lua-dbi-postgresql packages to work)
storage = "memory"

Here is my jitsi-meet config:

var config = {

at last I installed a new Jitsi-meet on a new Debian 10 machine and it worked just perfectly.

I think Jitsi team did a great job on installation packages!

Is there a way to list all ongoing calls with some details?
