Some other process is using the package management.

Do you still have the update manager or synaptic or something similar open? Or are you trying to install in parallel?

As the simplest solution a reboot should fix that.

Error installing ROS on Ubuntu 11.04

Error in step 1.3:

Then similar error in step 1.4 (in the install instructions):

sudo apt-get install ros-diamondback-desktop-full

From the terminal, I get the error:

Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

Help me please? :)
