Reassigning to qt4-x11 since those are the failing packages. A sample error below:

Unpacking replacement libqt4-scripttools:i386 ...
dpkg: error processing /var/cache/apt/archives/libqt4-scripttools_4%3a4.7.4-1ubuntu4_i386.deb (--unpack):
 './usr/share/doc/libqt4-scripttools/LGPL_EXCEPTION.txt' is different from the same file on the system

[Evan Huus (eapache)]

That makes sense. I found out that my package archive was broken after the upgrade because of this.

Eventually I ran

sudo rm /usr/share/doc/libqt4-scripttools/*
sudo apt-get -f install

to fix it.
