Please use the following command to refresh the public key

export DISTRO=focal-stable
wget -O -$DISTRO/public.key | sudo apt-key add -


@setq - this appears to still be down - current key states gpg: no valid OpenPGP data found.


Maybe you copied the number of clicks as well. It’s my fault, I changed the reply so that it doesn’t show the number of clicks.

This doesn’t actually allow you to do an update. When will the original issue be fixed?

sudo apt-key adv --keyserver --recv-keys 9B98116C9AA302C7

this worked for me.

Jesus ! please add this to the getting started page of the RADXA zero. Thank you!
