Hey all,

I'm a newbie and my problem is the terminal:

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?

Thanks, in advance.

You have another package manager running, whether that be apt-get, Software Center, Update Manager, Synaptic Package Manager, Adept Package Manager, ect ect.

You can only have one package manager running at a time.

Try closing all package managers or if that doesn't work, reboot and try again. ?
