Getting Validation Error in every setting I try to access

TrueNAS General
1

Hello everyone!

I have just installed my first instance of TrueNAS, and am consequently both new to the system and to the forum. I installed it on an old Fujitsu Celsius W420 workstation with an i7-3770 CPU, 8GB of non-ECC RAM, to a Samsung 850 PRO 512GB SATA SSD, with a Toshiba DT01ACA100 1TB HDD just to see what I can do. I used the 24.04.2.1 ISO to install.

Without having done anything else than installing, I get the same Validation Error whenever I try to change any setting or check for updates. I have searched the forum and the Jira tracker for anything similar, but came up empty. The error is this:

‘NoneType’ object has no attribute ‘get_attr’

To me, it looks like something is going on with IPv6, but I cannot access the network settings either. Can anyone tell me what I did wrong here or where I may find a solution?

Thank you and best regards

Not much help, but I’m also seeing the same thing on a long-time install of TrueNAS Scale for 25.04.2.4, and rolling back to my previous install for 25.04.2.1 seems to have resolved it for now…

The graphs on the dashboard page were broken too etc. All fine after rolling back though…

I had tried installing earlier versions, but got the same result. I then remembered that I had an issue in my Debian VMs where it would also disable IPv6 entirely for one interface and I could not figure out why. After some time, I managed to narrow it down to dhclient as the culprit. I switched that for udhcpc and everything worked.

My workaround in TrueNAS was temporarily redefining the VLAN on the switch port the TrueNAS machine was connected to. That way, it could not connect to the DHCP server on my Opnsense router and would not get an IPv4 DHCP lease. That gotr rid of the error message above and I could switch the interface to a static IPv4 address, taking dhclient out of the loop entirely, and everything has been running just fine since.
