Hey there!
So its been a while, and yes matrixos.ca is down.... I am hoping to get the site back up today. I am currently between moving houses, and have had other life events pull me away from my project.
I move into the new place August 21st, the next night I am setting the home lab and server back up, and during the next week I will have FRESH Trixie based ISOs built with a fun twist of the old Kubuntu theme backported :)
One issue I am running into is hosting my debian repo (it appears it makes my hosting service unhappy). However one goal, and this is where I think my solution has its upsides, once installed matrixOS is nothing more than a Debian system with Vanilla TDE on top, it simply swims on its own. I do not want a Q4OS situation where you are married to their repos going forward.
