dpkg: status database area is locked by another process

The Detail error message is : /* dpkg: status database area is locked by another process 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 error might arise frequently in linux. There can be other way of fixing the problem. I fix it by performing following step. 1. I run the “ rm /var/lib/dpkg/lock “ in terminal. 2. Then I run “ rm /var/cache/apt/archives/lock “ . Then I rebooted the linux(Ubuntu) Box.
