"Ubuntu" common error--could not get Lock/var/lib/dpkg/lock

Ubuntu Common error--could not get Lock/var/lib/dpkg/lockError during sudo apt-get install XXX via terminal installer:
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?

This problem may occur because another program is running, causing the resource to be locked out of service. The reason that the resource is locked may be that the last time you ran the installation or update did not complete properly, and then this situation, the solution is actually simple:
In the terminal, typing the following two sentences

sudo rm/var/cache/apt/archives/locksudo rm/var/lib/dpkg/lock

Try the installation again and solve the problem. Transferred from: http://hi.baidu.com/remoteexp/item/9a49be38da33155d81f1a7b7
