If Ubuntu MATE runs on Teres, I would imagine you could get Lubuntu or Alpine maybe to work as well. Have people put other Linux distributions than Ubuntu MATE and Armbian? Thanks.
Thank you information share.
I have installed Debian GNU/Linux 10 Buster and have upgraded it to 11 Bullseye.
I had installed vanilla Debian (by "vanilla" I mean an installation solely leveraging debian-installer and not using any vendor tools) and documented the process on the Debian wiki (https://wiki.debian.org/InstallingDebianOn/Olimex/Teres-I#Using_debian_installer).
Yes, I got all of them! :p
