Jitsi desktop does not work key error

debian 10

jitsi desktop does not work. Updating results in an
error about the jitsi key.

Is this the newest jitsi desktop deb version? Because
it is from Oct 2017.

Where do I get the jitsi key? From here:
Does it work? Thank you.

If you are trying to run the legacy desktop Sip and Xmpp client, that is the latest stable release as this is not the main focus of most of the developers in the community.

I uninstalled
Jitsi 2.10.5550
Then reinstalled them. Jitsi does not work.

Do you know if jitsi_2.11.5624-1_amd64.deb works?
