Thanks Sebastian, I don't understand the relationship between the output of apt-cache policy and the repository settings.
But I was configured to use edgy-security/main. I figured out what was missing: you had previously recommended edgy-updates/universe which I did, but for type 'deb' only. This made this entry unsymmetrical with the other repository entries, which had both 'deb' and 'deb-src'. When I enabled the 'deb-src' entry, I got the corrrect libgtk versions. This does then appear not to be a but with the library packages in question here, so I'll drop it. However, it appears to be a problem that a lot of people have. In my case, I have only altered the repositories carefully, and only when it was recommended that I do so. Yet it gets tangled up. But I don't know where to report this. I'll continue to think about it. -- [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
