I was trying to install TeamViewer, and I followed the instructions here even though they specify 11.10 instead of 12.04 (what I'm running).
In particular, I executed.
$ wget http://www.teamviewer.com/download/teamviewer_linux.deb $ sudo dpkg -i teamviewer_linux.deb
dpkg command failed, and after this point my packaging system has been broken. The software center instructs me to try:
$ sudo apt-get -f install
which leads to
Reading package lists... Done Building dependency tree Reading state information... Done Correcting dependencies... Done The following packages will be REMOVED: teamviewer7:i386 0 upgraded, 0 newly installed, 1 to remove and 17 not upgraded. 9 not fully installed or removed. Need to get 89.0 kB of archives.

At this point I'm stumped.
