WooHoo! DisplayCAL GUI for ArgyllCMS (color management system) is back in the Ubuntu/Mint repositories! The original developer of DisplayCAL, Florian HΓΆch, who for years did a fantastic job of building & maintaining DisplayCAL ceased development when Debian & its derivatives migrated from Python2 to 3. Erkan Yilmaz & team picked it up & ported it to Python3 a few years ago. It was very much an alpha patch, but it worked. Now it's fully functional & in the repositories again--nice! π π
