Hello André,
I've followed the step and the Update Manager has worked, but I've got a PSOD (attached photo) after host reboot.
After the first part I've reached the server via ping again (in the reboot procedure), but I've few minutes the ping has stopped again.
In the host there's installed an Intel Dual Port 10GB X540-AT2 (even if at the moment isn't used, but I'll need next month).
Any idea?
Regards
Luca
