Unable to find the GPG public key to verify Armbian_5.91_Helios4_Debian_buster_next_4.19.63.img - Signature made using RSA key ID 3ABD3FCD. Tried searching several key servers and the forum.
The key ID 9F0E78D5 listed on https://docs.armbian.com/User-Guide_Getting-Started/#how-to-check-download-authenticity can be found and is able to verify Armbian_5.91_Helios4_Debian_stretch_default_4.14.135.img
Has the new public key not been published or maybe I didn't search the correct server?
