No network connection after OMV 6 new installation

Hello
I have a problem with the new installation of OMV6,
I have the OS on my Raspberry pi-4-B-8GB
Raspberry Pi OS Lite
Release date: January 28th 2022 System: 64-bit Kernel version: 5.10 Debian version: 11 (bullseye) Size: 435MB

I did all the updates, including the preparation for OMV: sudo apt-get update
sudo apt-get upgrade -y
sudo rm -f /etc/systemd/network/99-default.link

then the installation link:
wget -O - https://github.com/OpenMediaVa…Script/raw/master/install | sudobash

and at the end of the installation comes this error:
"Error applying network changes. Skipping reboot!"

and if I start manually, the network configuration is gone and I have no access from the PC.

Could you please post the content of the following file:

Code

# cat /etc/netplan/20-openmediavault-eth0.yaml

I'm especially interested in line 16.

that's the result

Quote from votdev

Coudl you also please post the output of omv-confdbadm read --prettify conf.system.network.interface

that's the result

I have fixed the IP addresses
in /etc/dhcpcd.conf

but the error is also present if I do not change the IP.

and that is in /etc/network/Interfaces
as originally installed by OMV

There is an error in your DNS servers and gateway configuration. Remove the \n. The 192.168.1.1 is also added twice.

Where can I find this
I just edited the /etc/dhcpcd.conf
and there this entry is not to be seen.

Check you network settings in the GUI of OMV.

I can only work in the console

Where is the OMV folder

Quote from macom

reconfigure the network interface using omv-firstaid

Great thank you it worked
that's a great command
How can I enter a fixed IP?

Thank you for this great help
now everything works
best regards
