I've done a clean install of OMV (version 4.1.22-1) on a wiped unformatted sata M.2 SSD without any error messages, but in the end I have 2 problems.
Previously, I have had OMV 3.99 running without problems.
During installation I have left the root password to default (openmediavault)
I have created a user account 'willem'
After installation and first boot I get the message "no network interface(s) available".
However, during the installation was a connection for updating Debian available.
I've tried ipt addr and I got a message I don't understand.
2nd problem is I can't log on as root with the default username and password.
What am I to do to fix it?
The network device is not broken, because I have run a trail version of Ubuntu 18.04 from USB stick without changing the hardware setup and I get internet access.
