I tried to install MPlayer using apt-get. When i try this i get the following: linux:/home/daskas # apt-get install MPlayer Processing File Dependencies... Done Reading Package Lists... Done Building Dependency Tree... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. Since you only requested a single operation it is extremely likely that the package is simply not installable and a bug report against that package should be filed. The following information may help to resolve the situation: Sorry, but the following packages have unmet dependencies: MPlayer: Depends: libGLcore.so.1 but it is not installable Depends: libvgagl.so.1 but it is not installable E: Sorry, broken packages What package provides the above libraries? I now use the MPlayer 0.90pre4 which i installed from source without problems. Just curious to understand whats happening here. Thank you!
