Comment 5 for bug 1317028

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.
