Hi,
I think there a bug in omv-firstaid when i use it for change ip config i have an error :
Bash
root@omv3:~# omv-firstaid
Configuring network interface. Please wait ...
ERROR: address6: The value '' is not a string.
root@omv3:~#
At question 'Do you want to configure IPv6 for this interface' i anwser No
I think the mistake come into /usr/share/openmediavault/firstaid/modules.d/10configure_network.py
