After setting up everything, I wanted to install pip3 with apt, but it didn't work.
If I do ping google.com, nothing shows up on the screen. It's not my network because the openmediavault is working perfectly and ifconfig shows that eth0 and everything else is perfectly fine. It's really weird.
I'm using the Raspberry Pi 4 with the lite OS 64-bit, Ethernet with cable and a static IP that I set up with the openmediavault web interface...
I hope anyone can help me!!
