Jitsi-meet: Problems with Quick install

[ttjaden]

I have problems with the QuickInstall.
Ubutnu Server 16.04. LTS with nginx

The first time I installed I choosed the Option with my own Certs-Files by mistake and cancelled the installation within the process. The i removed "apt-get -y purge jitsi-meet" and made a second try with "apt-get -y install jitsi-meet". But then i wasn't asked anymore.

The Problem with the deinstallation with "apt-get purge jitsi-meet jicofo jitsi-videobridge" is that when doing "apt-get autoremove" afterwards the deinstallation of "jitsi-meet-web-config" fails with an error.

So the question is the a possibility to run the graphical configuration (FQHN and Certificate) by terminal account again? Or second: How to purge completely the whole installation?

[saghul]

Try this and start from scratch: sudo apt purge $(dpkg -l | grep -i jitsi | awk '{ print $2 }')

When having questions or problems can you first write to the mailinglist, before opening issues.

Normally if I want to purge all I do
apt-get --purge remove jitsi-meet jitsi-meet-prosody jitsi-meet-web jitsi-meet-web-config jicofo jitsi-videobridge.
When you have packages installed run this command, if you still have an error paste it here to be able to help.

@saghul your command will not purge jicofo. And also jicofo and jitsi-videobridge should be last or I have seen some errors when doing it...

May German is not fluent :) but can you follow these steps and paste the result:
See "systemctl status nginx.service" and "journalctl -xe" for details.
Maybe if you delete the nginx config for jitsi-meet purge will work, just a guess as nginx is the one complaining and jitsi-meet-web-config fails, cause it depends on reloading nginx.
You need to fix this command to pass: $ service nginx reload

Tanks! The Problem with nginx was:
nginx[28126]: nginx: [emerg] "server_names_hash_bucket_size" directive is duplicate in /etc/nginx/nginx.conf:63
I commented it out and then the purge worked. The new installation also worked and within that, I chosed fs-meeting.f1.htw-berlin.de as FQHN and choosed to generate self-signed certs.

Now JITSI MEET is working. So the next steps would be to change the SSL-Certs by letsencrypt SSL-Certs. I generated the certs a few days ago and now changed the *.conf file to this one

`erver_names_hash_bucket_size 64;

server {
listen 80;
server_name fs-meeting.f1.htw-berlin.de;
return 301 https://$host$request_uri;
}
server {
listen 443 ssl;
server_name fs-meeting.f1.htw-berlin.de;

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
ssl_ciphers "EECDH+ECDSA+AESGCM:EECDH+aRSA+AESGCM:EECDH+ECDSA+SHA256:EECDH+aRSA+SHA256:EECDH+ECDSA+SHA384:EECDH+ECDSA+SHA256:EECDH+aRSA+SHA384:EDH+aRSA+AESGCM:EDH+aRSA+SHA256:EDH+aRSA:EECDH:!aNULL:!eNULL:!M$

add_header Strict-Transport-Security "max-age=31536000";

#ssl_certificate /etc/jitsi/meet/fs-meeting.f1.htw-berlin.de.crt;
#ssl_certificate_key /etc/jitsi/meet/fs-meeting.f1.htw-berlin.de.key;
ssl_certificate /etc/letsencrypt/live/fs-meeting.f1.htw-berlin.de/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/fs-meeting.f1.htw-berlin.de/privkey.pem;


root /usr/share/jitsi-meet;
index index.html index.htm;
error_page 404 /404.html;

location /config.js {
    alias /etc/jitsi/meet/fs-meeting.f1.htw-berlin.de-config.js;
}

location ~ ^/([a-zA-Z0-9=\?]+)$ {
    rewrite ^/(.*)$ / break;
}

location / {
    ssi on;
}

# Backward compatibility
location ~ /external_api.* {
    root /usr/share/jitsi-meet/libs;
}

# BOSH
location /http-bind {
    proxy_pass      http://localhost:5280/http-bind;
    proxy_set_header X-Forwarded-For $remote_addr;
    proxy_set_header Host $http_host;
}

}
`
But then I get an error: NET::ERR_CERT_AUTHORITY_INVALID

[damencho]

Works fine here, I see your certificate ok.

Tanks a lot. Must have been the browser cache. I Firefox it works but in Chrome there is still an Cert-Error. Despite of that:
Where I find information on howto:
-- secure the app with login
-- enable screen sharing
-- shared notes

P.s. Perhaps a recent example nginx conf-File would be reat to find out, why chrome has an error about the SSL-Cert.

Tanks a lot!

[damencho]

For authentication take a look: https://github.com/jitsi/jicofo#secure-domain
For screensharing: https://github.com/jitsi/jidesha/tree/master/chrome for chrome, for newer FF versions (52+) you do not need anything, for older you can create an extension again take a look at jidesha project.
For shared document, there is no documentation, you just need to install etherpad and set its link to access it in config.js.
