I tried a "sudo apt update" after I had sucessfully completed a "sudo apt upgrade" via SSH using Putty.
Unfortunetlay, with the latest firmware version v2.0.5 (MCU2) I am getting the following error message:
Err:10 http://deb.volian.org/volian scar InRelease
Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)
Hit:9 http://netcup.armbian.com/apt jammy InRelease

N: Updating from such a repository can't be done securely, and is therefore disabled by default.

Can you maybe explain to me, how I can solve this issue? Thanks for your support!
