On Ubuntu Studio I ran into an issue installing ToneLib-GFX. It was telling me that the libgl1-mesa-glx dependency was missing on my system.

Here’s my notes on the two ways I could get this solved. Note: ToneLib-GFX-amd64.deb file is in my Downloads directory.

Download/Command Line

Download the package. I got it at pkgs.org but I’m sure you can find it all over the place.

This will, of course, put it in your Downloads folder

cd to Downloads, then:

$ sudo dpkg -i libgl1-mesa-glx_22.3.6-1+deb12u1_amd64.deb

Once this runs, then install ToneLib:

$ sudo dpkg -i ToneLib-GFX-amd64.deb

Command Line Only

Update apt

$ sudo apt update

Install the package

sudo apt -y install libgl1-mesa-glx

Once that’s complete, install ToneLib

$ sudo dpkg -i ToneLib-GFX-amd64.deb
