The forum

so I just clicked out of the terminal window. I'm guessing I needed to select "okay" to finish installing or open the app or something. either way I don't see the app anywhere. I'm new to linux btw and I only checked the app that searches your computer and found nothing. do i have a run the terminal commands again and find a way to click okay on the user agreement first?

I tried again and got this:

ben@Hal:~$ sudo apt-get install playonlinux
[sudo] password for ben: 
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?

help? thanks
