[pkg-nvidia-devel] Bug#575272: nvidia-glx: removes file belonging to libgl1-mesa-dev on purge

[Sven Joachim]

Package: nvidia-glx
Version: 190.53-1
Severity: serious

Purging nvidia-glx results in /usr/lib/libGL.so (a symlink belonging to
libgl1-mesa-dev) being deleted, as can be seen in the following

The reason is that the postrm removes the /usr/lib/libGL.so symlink on
both removal and purging, and in the purge case the diversion that the
nvidia-glx preinst had set up is already gone.
