Server Installation Failed Debian 11

Heya,

Since Wednesday last week I have been trying to install a Workspace Server using the provided scripts.
I have attempted Debian version 11, 12 and 13.

Currently using Debian Version 11 I get following error.


 deb [signed-by=/usr/share/keyrings/mono-official-stable.gpg] https://download.mono-> project.com/repo/debian stable-bullseye/snapshots/6.8.0.123 main
 gpg: keyring '/usr/share/keyrings/mono-official-stable.gpg' created
 gpg: keyserver receive failed: No route to host

This seems to be a reoccurring issue, looking at threads like,

OS: Proxmox Debian 11.11

Attempting Installation using the Enterprise Installation script results in following errors

Hey @k.schwarzer, :wave:

Sorry for the long wait!
Is the installation issue still happening for you?
