So I've reinstalled my OMV after some issues, now my computer runs OMV 4.1.22 and I was going through the setup procedure when GParted started to complain. Error message in picture.
OMV is fresh, I've run 'apt-get update' then 'omv-initsystem' to finish it. I've installed Midnight Commander, hddtemp and Net-Tools.
Please help. I'm new at Linux.
