Package update ubuntu public signature

#1

when I try to update the ubuntu installation installed from the radxa download page I get the following errors:

Err:5 http://apt.radxa.com/focal-stable focal InRelease
  The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 9B98116C9AA302C7
Reading package lists... Done
W: GPG error: http://apt.radxa.com/focal-stable focal InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 9B98116C9AA302C7
E: The repository 'http://apt.radxa.com/focal-stable focal InRelease' is not signed.

something about the update is unable to occur because the public key is not available. Is there some setup step I missed?

The public key for the radxa server has expired
Run the following:

sudo apt install wget
wget -O – apt.radxa.com/focal-stable/public.key

A bit disappointing that Radxa didn’t fix this, but I guess that’s the price you pay for buying Chinese RPi clones:)
Thanks to @Greenbeans, this worked for me (I’m using bullseye, Rock4SE)

wget -qO - apt.radxa.com/bullseye-stable/public.key | sudo apt-key add -

I hope it helps for others as well!

A very good example of not giving a flying duck.
