The only reason this happens is when you have conflicting lists of packages in multiple repositories. This is usually caused by using PPA's with conflicting packages, and from what I can see, you have a bunch of PPA's installed, and packages dependent on each other must be fighting for dependencies and versions of those specific packages. They are commented out, sure, but I think that however you have been managing packages is messing things up. From the screenshot you posted, your problem is likely with the xorg-edgers PPA, as you have it commented out, it can no longer see those versions of those packages, and therefore needs to uninstall them. This is not a PlayOnLinux issue, as no one is reporting this. This is specific to your package manager, as it is broken from package conflicts. It is not a bug. Please remove all PPA's, downgrade your packages, and try to install PlayOnLinux again.
