Comment 6 for bug 349781

I've done some testing. I think it's a dependency thing.

The dependencies for hplip-gui in Intrepid are:

libqt4-assistant
libqt4-help
libqt4-svg
libqt4-test
libqt4-webkit
libqt4-xmlpatterns
python-qt3
python-qt4
python-qt4-common
python-reportlab
python-sip4 ttf-dustin

In Jaunty the dependencies are:

libaudio2 (1.9.1-5)
libmysqlclient15off (5.1.30really5.0.75-0ubuntu9)
libphonon4 (4:4.3.1-0ubuntu1)
libqt4-assistant (4.5.0-0ubuntu2)
libqt4-dbus (4.5.0-0ubuntu2)
libqt4-designer (4.5.0-0ubuntu2)
libqt4-help (4.5.0-0ubuntu2)
libqt4-network (4.5.0-0ubuntu2)
libqt4-opengl (4.5.0-0ubuntu2)
libqt4-qt3support (4.5.0-0ubuntu2)

libqt4-xml (4.5.0-0ubuntu2)
libqt4-xmlpatterns (4.5.0-0ubuntu2)
libqtcore4 (4.5.0-0ubuntu2)
libqtgui4 (4.5.0-0ubuntu2)
mysql-common (5.1.30really5.0.75-0ubuntu9)
phonon (4:4.3.1-0ubuntu1)
phonon-backend-gstreamer (4:4.3.1-0ubuntu1)
python-qt4 (4.4.4-2ubuntu5)
python-qt4-common (4.4.4-2ubuntu5)
python-qt4-dbus (4.4.4-2ubuntu5)
python-renderpm (2.3-0ubuntu1)
python-reportlab (2.3-0ubuntu1)
python-reportlab-accel (2.3-0ubuntu1)
python-sip4 (4.7.9-1ubuntu1)
python2.5 (2.5.4-1ubuntu3)
python2.5-minimal (2.5.4-1ubuntu3)

Somehow those dependencies are not getting updated during an upgrade from Intrepid to Jaunty Beta.

I'll gladly do any testing you want! (as time allows)
