Problem installing on Vhost with Debian 8

Hi,
I am trying to install jitsi on a Vhost with Debian 8:
PRETTY_NAME=“Debian GNU/Linux 8 (jessie)”
NAME=“Debian GNU/Linux”
VERSION_ID=“8”
VERSION=“8 (jessie)”
ID=debian
18.0.25.2
Plesk Obsidian 18.0

When using apt-get -y install jitsi-meet

I am getting the following messages:

Reading package lists… Done
Building dependency tree
Reading state information… Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
jitsi-meet : Depends: jicofo (= 1.0-544-1) but it is not going to be installed
PreDepends: jitsi-videobridge2 (= 2.1-169-ga28eb88e-1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

I am not really a server admin speciallist. Thanks for any help.

have you installed java openjdk 8? it’s required!

apt-get update
apt-get install openjdk-8-jdk-headless

maybe some errors (unable to locate) … my suggestion, update debian first:
https://www.howtoforge.com/tutorial/how-to-upgrade-debian-8-jessie-to-9-stretch/

have you added the package repository to your apt source-list? plus “apt-get update” after
https://github.com/jitsi/jitsi-meet/blob/master/doc/quick-install.md#add-the-jitsi-package-repository

what is the output on command “hostnamectl” ? especially kernel and architecture
packages support just for amd64 (if i got it right)

Many thanks for the support. According your proposals I updated to Debian 9.12‬, installed java and installed jitsi again. Now it is running:

org.jitsi.jicofo.Main --host=localhost --domain=XXXXX.XXXXX.XX–port=5347 --secret=XXXXX–user_name=focus --user_domain=auth.XXXXX.XXXXX.XX–user_password=XXXXXX

When calling the used subdomain name I am getting no Jitsi page in the browser.

I am running Plesk 18.0.26 with 3 different sub domains. One of the subdomains I wanted to use for Jitsi. I put the subdomain name into the /etc/hosts:

127.0.0.1 server.XXXXX.XXserver XXXXX.XXXXX.XXlocalhost

I expect that I need to change nginx config files?

Any further ideas?
