If you feel more at ease with a graphical interface, launch the "Synaptic  
Package Manager" (in the "System Settings"), click the "Custom Filters"  
button (in the bottom-left part of the window) and choose "Broken" (above).  
You can then try to 1. remove the broken packages (listed on the right), 2.  
update the system without broken packages, and 3. reinstall (some of) the  
packages you removed at step 1. Just pay attention to what will actually be  
removed before confirming (i.e., after pushing the "Apply" button): you do  
not want to remove most of your system!
