When I try install or remove a software through the terminal, I receive

dpkg package was interrupted

and further if I use software center to install the same, I receive

ttf-mscorefonts-installer errors

I tried to solve the same using

sudo apt-get update && sudo apt-get upgrade

and I receive

E: Could not get lock /var/cache/apt/archives/lock - open (11: Resource temporarily unavailable)
E: Unable to lock directory /var/cache/apt/archives/

Try running sudo dpkg --configure -a in a terminal and see if that helps.

If you find you still have a lock it is because the system thinks you still have something using apt.

Close any Software Centre/Synaptic/terminal running an apt command. Reboot if the lock still shows or run from a terminal

sudo rm /var/lib/dpkg/lock

There should have been an EULA to agree to - tab to OK and enter once the sudo dpkg --configure -a command is running.

sudo dpkg --configure -a should work without needing to purge the lock, you don't need to rm the lock (you should never do that anyways) – Thomas W. Apr 20 '12 at 7:50
