I dont know what's wrong with my update manager..

It says that the softwares that I installed was broken. Maybe because I force shutdown my laptop, because Ubuntu wont shutdown,showing up desktop wallpaper but not title bar and launcher, but It won't shut down (+that's another bug).

I've just update the broken softwares. the size is 60 to 70 MB..

But It doesn't work. Now I cannot update or install any software from Update Manager or Ubuntu Software Center. Can anybody tellme what's wrong?

This is what appears when I use Update Manager

I use Ubuntu Software Center, and this message appeared

I chose repair and when it update the broken softwares using Ubuntu Software Center.
It failed. And show up this message.

The problem is I can't update or install any program from Ubuntu Software Center and Device Manager anymore. (I closed allprograms include ubuntu software center,and device manager in this case). Some one helpme?

I tried to use apt-get install -f in terminal but it shows message like this:

E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
