Raspberry Pi 4 and OpenMediaVault

Hello, I am currently in the process of setting up a NAS system with OpenMediaVault on my Raspberry Pi 4B. When I execute the install script from OpenMediaVault, everything works fine. At the end, it says that everything has been successfully created, and then the script restarts my Raspberry Pi:

yaml

Total run time:    3.513 s
[2024-02-11 13:35:19+0100] [omvinstall] Network setup.  Rebooting...

I get kicked out of my SSH session. However, I cannot reconnect afterward. On my router, I can see that the Raspberry Pi is connected to the Wi-Fi network. However, I cannot access the OpenMediaVault page, and I cannot connect via SSH. When I ping the Pi (using the Ping command in the Windows cmd):

Connect a display to HDMI0 and report back the message.

it say's "A start job is running for Wait for Network to be Configured (57s / no limit)"

after a while it says "Failed to start Wait for Network to be Configured"

and prompts me with the normal login screen

and now the os works completely fine except that I cannot connect to anything

I've tryed to set the wifi via the raspi-config menu. But it says "No supported Network connection Manager found"

okay, it seems like OMV uninstalls the NetworkManager but how do I re-install it? (without a internet connection)

That is a cumbersome process. You need to find the packages (.deb) for network-manager and then you also need to install eventual dependencies.

And in some point you need to download packages. So I hope you have a second computer...
