I am getting the following error whenever I try to install anything using apt-get install:
liam@Liam-Tosh-Linux:~$ sudo apt-get install chromium-browser
[sudo] password for liam:
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?
What is causing this error?
