Thread: problem in dpkg configure

hey guys,
installing s/w in ubuntu through terminal. when tried install 3rd s/w, said
"administrator directory cannot unlocked, because used process".
killed dpkg process forcefully , performed
sudo dpkg --configure -a.

i got following output,

dpkg: many errors, stopping

processing halted because there many errors.

error because dpkg crashed? how recover it? how install s/w after this?

in advance

"used process" means have more 1 package manager open , need close other(s).
