Saving interface configuration: failed

[ReciprocalMoonlight]

Hi, I'm currently setting up a TrueNAS Scale box and accidentally borked the network connection. I had a working static IP set up on one of my NICs (the system has an Intel 2.5Gbit NIC on the motherboard and a quad 1Gbit Intel PCIe card, the static interface was on one of the 1Gb NICs), but wanted to switch to the on board NIC for virtualisation purposes. I attempted to do this via the console locally because I needed to detach the old interface from the IP to set up the new one, but after removing the existing network interfaces it won't let me save anything, it just gives me the error "Saving interface configuration: failed". This seems to happen no matter what I try, DHCP or static, different NICs, nothing helps.

Is there any way to fix this or do I have to reinstall from scratch?

If you're at the console, I'd remove all network config, then bring it back one item at a time.

You'll want to only have one interface (or even none) using DHCP in the final setup.

How do I do that? There's no option I can see to reset all networking unless I reset everything for the entire install.

Have a look at what your options can be:

Cannot Change IP on Interface through GUI

I am trying to set an IP on one of my interfaces and it will not save. Within the GUI I go to the interface and disable DHCP and Autoconfigure IPv6 and it allows me to enter in an Alias. I enter in 10.0.1.2/24 and hit save and nothing changes. A small progress bar at the top of the small config...

To spell that out a little more:

1. Configure Network Interfaces

Then you can delete them all from the list with the Delete key

Then N to add new ones back as you need.

Thanks, it turns out the issue was that I was using an out of date command to get to the CLI and was in the Core version by mistake, that link mentioned the issue and that it breaks things, as well as how to invoke the correct UI. That got me up and running.
