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
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?
