NethServer Version: 7.7
For more than 2 years now we could not update from GUI (neither “old” one, nor Cockpit).
So we managed to update only from console using yum update.
We always got strange error massages, not usable for problem solving.
Because we were still trying to use the GUI update method we found, after the last update a new massage which lead us to a solution- https://access.redhat.com/solutions/158883
So the problem was a double installed package, which hang the whole update process.
Hope that helps somebody.
