I need to install mesa 20.x for Unity3D. Using ubuntu 20.04.
I tried the two ppas (ppa:kisak/kisak-mesa and oxxx) but there version is more recent than ubuntu. How can I do this?
see bug report
I tried sudo apt-get install -f libgl1-mesa-dev=20.0.4-2ubuntu1 but I get the following message:
The following packages have unmet dependencies: libgl1-mesa-dev : Depends: libgl-dev but it is not going to be installed Depends: libglvnd-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.But libglvnd-dev is already installed
libglvnd-dev is already the newest version (1.3.2-1~ubuntu0.20.04.1).
