Unmet dependencies error
 

found errors while doing dpkg --configure -a , tried doing apt-get install -f still not working
Errors were encountered while processing:
python-aptdaemon
python-gi
glib-networking

software-center
libpython2.7-stdlib

Did you try 'apt-get update' and after that 'apt-get -f install'? And, after those 2, try, 'dpkg --configure --pending'. If you still can't get it to work, fire up 'synaptic', hit reload, and remove the broken packages. Then, start over.
