can not install software in linux error as dpkg was interrupted

Question

I was trying to install mono using following commands,

1. sudo apt-get install mono-*

unfortunately, I closed the terminal while it installing. again i started to reinstall but shown error like

Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)

I tried below commands for solution,

1. sudo rm /var/lib/apt/lists/lock
2. sudo rm /var/cache/apt/archives/lock

But now I am getting the error like

dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.

how do I fix this one?
