Sebastian, The problem plainly has nothing to do with Adept or Kubuntu, per se. It is a package problem.
It might be that I have mis-configured my repositories somehow, but besides enabling the repositories that were provided by my distro, the only repository I have enabled was the one you suggested. The bug persists, and we don't know what its root is. You seem to know something about repositories...can you look again at the ones I have enabled, and see if something is amiss? -- [Edgy] Broken packages while trying to install libgtk2.0-dev https://launchpad.net/bugs/49220 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
