Hi, tried to install, and got the following: me@Parker:~/Downloads$ sudo apt install ./ToneLib-GFX-amd64-4.7.deb Reading package lists... Done Building dependency tree Reading state information... Done Note, selecting 'tonelib-gfx' instead of './ToneLib-GFX-amd64-4.7.deb' tonelib-gfx is already the newest version (4.6-6). 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. (I renamed the file when I downloaded it, as you always use the same name) thanks!
