Ok folks, first, sorry if my english is not very good.
Im testing the new Ubuntu 11.10 with Unity, well, that's not the point, the point is that a realized a time ago that when im installing something I can't install other thing, I need to wait to install the first thing after installing the other.
An example, I entered in a terminal "sudo apt-get install ubuntu-restricted-extras" in order to get the restricted extras. Later in another terminal I entered "sudo apt-get install fping" and I got the next message:
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?
My question is: Can I install, use or do something in order to install many things at the same time?
