Whenever I am trying to install unity tweak tool through command line, this message shows up

E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

How to rectify this ?

Make sure that you have not opened other programs that use dpkg like the Software Manager or the software updater and try again.
