Errors were encountered while processing:

E: Sub-process /usr/bin/dpkg returned an error code (1)
after this error apt (or nvidia-glx) create dpkg-divertions witch
prevent installing(for purging) both nvidia-flx and nvidia-glx-legacy.
eatch of the packages will say that the other one is installed (glx
vs legacy).
to fix it you should :
list divertions.
debian:/home/mha13# dpkg-divert --list nvidia-glx-legacy
diversion of /usr/lib/xorg/modules/extensions/libGLcore.a to /usr/lib/nvidia/libGLcore.a.xlibmesa by nvidia-glx-legacy
diversion of /usr/lib/xorg/modules/extensions/libglx.a to /usr/lib/nvidia/libglx.a.xlibmesa by nvidia-glx-legacy
diversion of /usr/lib/xorg/modules/extensions/libglx.so to /usr/lib/nvidia/libglx.so.xlibmesa by nvidia-glx-legacy
then remove the diverstions.
dpkg-divert --rename --remove /usr/lib/xorg/modules/extensions/libglx.a
dpkg-divert --rename --remove /usr/lib/xorg/modules/extensions/libglx.so
dpkg-divert --rename --remove /usr/lib/xorg/modules/extensions/libGLcore.a
and now you can install freely the nvidia-glx.
the issue with the bug that apt(or nvidia-glx) create divertions even if
it is not installed (exit with error)
