You can use a live system from an install DVD / USB stick and start a 
clean install. However at the partitioning stage be very careful. Select 
manual partitioning. Select your current partition for "/" with the same 
file system type and make sure that the partition will not be formatted. 
Then at least "/home/" and "/usr/local/" are retained. Anyway I would 
suggest to make a backup of your valuable data first. And don't forget 
to include the directories "/etc/" and "/var/".

You can log in at the terminal and enter these commands:

sudo configure -a
sudo apt-get -f install

It may be necessary to repeat the commands several times until the 
interrupted install process is finished. At the prompt for the licence 
agreement use the TAB key to select the OK prompt.
