No remote video audio in conference when participant is using Chrome52 browser

Problem:

No remote video/audio in conference when participant is using Chrome52+ browser

Solution:

To fix the issue with the missing remote A/V in video-confrences where a participant uses google-chrome 52 and newer, jitsi needs to be updated.

Backup important configuration files :

1). Login to to the talk-server and backup your config files to you home directory :

cd ~
mkdir configbackup
cd configbackup
sudo cp -rp /etc/jitsi /etc/nginx /etc/prosody /etc/zimbra-talk ./

2). Update your system

sudo aptitude update
sudo aptitude full-upgrade

3). Restore /etc/jitsi configuration (normally this should be enough, the other config-files were just backuped to be on the save side, in case it's a very old installation and other components are updated during the process as well) :

sudo cp -rp jitsi /etc/

4). Reboot the talk-server

sudo reboot
