ProxMox: error apt-get exit code 100

Kept on getting error messages in my ProxMox-environment:

apt-get error

When running ”apt-get update” manually in the shell, I got some error messages, ”unauthorized”:

So, what to do? After a short googeling I found that the change I need to made was in the /etc/apt/sources.list.d/pve-enterprise.list

Comment out the whole row by using a ”#” char. Save and exit.

The reson for this that the update is trying to fetch updates which are only for subscribing installations. Since I’m running a test-environment I have no subscription. Which lead to problem… Well, case closed now!
