I tried today to install a dvb-card on my Ubuntu 12.04 (Linux blauhai-linux 3.2.0-25-generic #40-Ubuntu SMP Wed May 23 20:30:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux ). The installation failed with an error. After that, i tried to install python (it was already installed but i got this error):

linux:~$ sudo apt-get install git
Reading package lists... Done
Building dependency tree

Reading state information... Done
git is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 python-glade2:i386 : Depends: python:i386 (< 2.5) but it is not going to be installed
                      Depends: python-support:i386 (>= 0.3.4) but it is not installable
                      Depends: python:i386 (>= 2.4) but it is not going to be installed
                      Depends: libglade2-0:i386 (>= 1:2.5.1) but it is not going to be installed
                      Depends: python-gtk2:i386 (= 2.8.6-8) but it is not going to be installed
 python-numeric:i386 : Depends: python:i386 (< 2.5) but it is not going to be installed
                       Depends: python:i386 (>= 2.3) but it is not going to be installed
                       Depends: python-central:i386 (>= 0.5.7) but it is not installable
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

well, i can read and tried the proposed command, but then i get this:

linux:~$ sudo apt-get -f install
