When trying to install any package in a terminal, I get the following error

Not possible to block /var/lib/dpkg/lock - open (11: Temporaly not available resource )

This started happening after trying to install Microsoft font libraby. It stopped at:

"ttf-mscorefonts-installer" configuration window

This has already been answered - Fixing Could not get lock /var/lib/dpkg/lock. Just run:

sudo fuser -cuk /var/lib/dpkg/lock; sudo rm -f /var/lib/dpkg/lock

Hey the problem is simple probably your previous installation of software was interrupted.Hence the lock file is still locked by the previous installation.Do this thing it may help try again to install the software ,if still the error comes then reboot the system and try the software center to install a software.
