dpkg wont convert a directory to a symlink or vice-versa on upgrades; that is if an older version of ubuntu-docs used to ship a /foo/bar symlink and the new version ships a /foo/bar dir, it will result in a symlink. (This is considered a feature of dpkg which allows symlinking e.g. /usr to /mnt/large-space-device).
So I'd look at the .deb history and see whether it used to ship a directory in place of the symlink and fix this in the preinst. -- System->About Ubuntu homepage has glitchy "Thank you" line https://bugs.launchpad.net/bugs/303578 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
