Unmet depencies error

Hi,

Can anyone give me suggestion on following error.

The following packages have unmet dependencies:
jitsi-meet : Depends: jitsi-videobridge (= 1126-1) but it is not going to be installed
Depends: jicofo (= 1.0-508-1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

I have installed java 8 on my debian 8.11 server and trying to use sudo apt-get -y install jitsi-meet

But getting unmet dependencies error.

Packages depend on systemd does Debian8 have it?
