I upgraded from 4 to 5 by the way that has @ryecoaaron described in Post #38 in this thread.
It runs but the main field "Overview" at "System Informations" is blank In the other tabs (processes,...) are datas and I see it´s really OMV 5 now.
What have i to do?
After rebooting the same problem and additional I can´t install docker "DNS Error".
Is the upgrade not really full and clean?
How can I "repair" it?
