This is what worked for me: First: remove hardy-backports from sources.list!
$ sudo apt-get update $ sudo apt-get install -d libqt4-core=4.3.4-0ubuntu3 libqt4-gui=4.3.4-0ubuntu3 libqt4-sql=4.3.4-0ubuntu3 libqt4-qt3support=4.3.4-0ubuntu3 (get qt 4.3, download only as installation will fail anyway) $ sudo dpkg -i --force-overwrite /var/cache/apt/archives/libqt4-core_4.3.4-0ubuntu3_i386.deb (force installation of qt 4.3 core) $ sudo apt-get install libqt4-gui=4.3.4-0ubuntu3 (try installation of qt 4.3 gui, installation fails, but it removes some conflicts of qt 4.3 gui) $ sudo dpkg -i --force-overwrite /var/cache/apt/archives/libqt4-gui_4.3.4-0ubuntu3_i386.deb (now force installation of qt 4.3 gui) $ sudo apt-get autoremove (remove some packages that have now become obsolete, this also removes psi on my computer, but we can reinstall it later) $ sudo apt-get remove libqtcore4 libqtgui4 (now remove the last bits of qt 4.4, this also removes lastfm on my computer, we will reinstall it later) $ sudo apt-get install --reinstall libqt4-core libqt4-gui (reinstall qt 4.3 core and gui, just to be sure) $ sudo apt-get install libqt4-sql libqt4-qt3support psi lastfm (install qt 4.3 sql and qt3support, also reinstall psi and lastfm (you mileage may vary)) -- Closing chat dialog in Psi closes the whole Psi https://bugs.launchpad.net/bugs/228146 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
