I had the same problem with NO_PUBKEY 93D6889F9F0E78D5 from APT UPDATE when I reinstalled Armbian 22.05.3 on my Banana Pi. Use this command to get the PUBKEY from the Ubuntu Keyserver and write it correctly to /etc/apt/trusted.gpg.d: wget http://keyserver.ubuntu.com/pks/lookup\?op\=get\&search\=0xdf00faf1c577104b50bf1d0093d6889f9f0e78d5 | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/armbian.gpg

I was able to upgrade Armbian to 18.04 bionic beaver on my Banana Pi M1, and it's working (almost) fine! I used the command to update the sources.list to bionic: apt update && apt dist-upgrade -y && apt autoremove -y && apt autoclean apt install update-manager-core do-release-upgrade -d Fetched 403 MB in 8min 43s (769 kB/s) I gave "yes to all" to almost everything, except on replacing config files like KEYMAP, sshd and bind All these services I use are working correctly: network, SSH, bind, mail, cups, minidlna, SATA, USB printer, Samba This is not working: qbittorrent-nox 4.0.4 (misses libboost-system) Don't try to upgrade if you don't know what you are doing and if you can't handle some instability. If you managed to do a successful upgrade, post your thoughts/problems to this topic!
