Rock Pi 4B+ - Ubuntu Focal Server apt NO_PUBKEY

ROCK 4 Series Troubleshooting
1

I set up my Rock Pi 4B+ as my print server, and every time I ran apt update, this always shows up

Err:1 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

The image I used was from here because I initially had some trouble finding the wiki2 website for some reason. But even one from there fails to fetch from that source. To be clear, this is not causing me trouble, but it might be worth fixing so it wouldn’t potentially come back to me.

Thanks.

Hi,

According to the error message, the error reason is that the public key is not available. By reading the information from http://apt.radxa.com/. I think a public key for focal-stable can be imported using the following command:

wget -O -  apt.radxa.com/focal-stable/public.key | sudo apt-key add -

Can you give it a try and see if the error message is still present?

Huh, that seemed to work. Thanks! Weird that they didn’t list one for focal.
