```

Add Jitsi Repository

Download the Jitsi repository and import the GPG key:

wget https://download.jitsi.org/jitsi-key.gpg.key sudo rpm --import jitsi-key.gpg.key

Create a new repo file for Jitsi:

sudo nano /etc/yum.repos.d/jitsi.repo

Add the following lines:

[jitsi] name=Jitsi baseurl=https://download.jitsi.org/stable/ gpgcheck=1 gpgkey=https://download.jitsi.org/jitsi-key.gpg.key enabled=1
