Comment 35 for bug 249340

I had to set synaptic source to us main server.
that was after using options to get the gui to come in the safe mode.
restarted computer
picked 14 instead 0f 15 used regular log in
it hung at gui
restarted computer
picked options instead of logging normally
chose terminal option
then ran
sudo apt-get dist-upgrade
sudo --configure -a

it worked, I dont know how or why, but I thank all for your help
