You would get this message few times, while you abort the download in your linux based machine.
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?
and that is not a risky thing to clear it.
The reason is beause of the lock placed during installation, Here's how you can do that .
Open the terminal and type the following commands,
sudo rm /var/lib/apt/lists/lock
sudo rm /var/cache/apt/archives/lock
