Aha. I tried installing the kde-window-manager explicitly, which then reported a similar 'Depends:...' error, and the same for that dependency until discovering the apparent bottom line:
libplasma3: Depends: kdelibs5-data (= 4:4.2.0-0ubuntu2~intrepid2) but 4:4.2.2-0ubuntu1~intrepid1 is to be installed -- kdelibs-bin says it has a dependency which is only available in backports https://bugs.launchpad.net/bugs/354927 You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kde4libs in ubuntu. -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
