Some of you may experience this error in your life if you are using linux .it happens when previous installation fails , here is the screenshot which is happened in my Linux Distro

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?

 its very easy to fix this error just type following commands in your terminal

sudo rm /var/lib/dpkg/lock  

this will delete the “lock” directory in /var/lib/dpkg/
