I fixed this case by re-installing the 64bit version of libqtcore4. Using aptitude I did this: aptitude re-install libqtcore4 aptitude install libqtcore4:i386 (aptitude install skype) I was trying to install skype too. ** This bug has been marked a duplicate of bug 918765 the file '/etc/xdg/Trolltech.conf' is in two packages -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to qt4-x11 in Ubuntu. https://bugs.launchpad.net/bugs/993110 Title: package libqtcore4 4:4.8.1-0ubuntu4.1 failed to install/upgrade: conffile './etc/xdg/Trolltech.conf' is not in sync with other instances of the same package To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qt4-x11/+bug/993110/+subscriptions -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
