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/
