To all Debian users who are experimenting problems to install Trinity.

There was a bug with Qt3 versioning, in the Debian version of Trinity 3.5.13.
(http://bugs.pearsoncomputing.net/show_bug.cgi?id=583)

If the following command:
  dpkg -l|grep 3:3.3.8-d-0ubuntu0
is listing some packages, you'll have to force a "downgrade" from version
"3:3.3.8-d-0ubuntu0+sr73+pr181~squeeze" to version
"3:3.3.8d-0ubuntu0+sr73+pr181~squeeze".

Here is a script to do the job:

OLDVERSION=3:3.3.8-d-0ubuntu0+sr73+pr181~squeeze
NEWVERSION=3:3.3.8d-0ubuntu0+sr73+pr181~squeeze
for f in `dpkg -l | grep $OLDVERSION | awk '{print $2}'` ; do
  apt-get install $f=$NEWVERSION
done
