Problem update after upgrade from 15 to 16

Hello. I have problem after i upgrade my WS and GW from 15 to 16 whonix.
When i start update via system trey, in Qubes Updater i see error: "Rendering SLS ‘base:update.qubes-vm’ failed: Jinja variable ‘dict object’ has no attribute ‘os_family’.
This happens to all templates with WS 16 and GW 16.
I have clear WS 16 template and with my settings - doesn’t matter. Also i tested with other templates - debian 10, whonix 15 - all ok. And from terminal in whonix 16 i can update correct.
How i can fix it?

remove and install fresh isnt that better? (surely by understanding and following the wiki steps as well)

Hello, welcome back!

This error message isn’t part of any Whonix source code.
Qubes updater isn’t developer by Whonix.
It’s a Qubes issue. Not a Whonix issue.

See: What to post in this Qubes-Whonix forum and what not.

sudo apt update
sudo apt upgrade
type in templates terminal, for me worked
