When trying to install lmms (from any source; software center, kxstudio ppa), it asks for removal of nvidia-libopencl1-331-updates. I'm not sure why this would be an issue, as the two packages have little to do with one another. Anyways, does anyone know why this is occuring?
What version of Ubuntu are you using?
