what does this msg mean

[corky383]

I was trying to install various extras in order to install rubyripper

sudo apt-get install flac lame mp3gain normalize-audio ruby-gnome2 ruby vorbisgain

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?


Is it something to do with my repositories?

Only one application can act on the source lists at a time. This message is telling you that apt-get was unable to install the files because another program was using them. Make sure the Update Manager, Synaptic, and any other instances of apt-get or aptitude are down.

This usually happens when you have the GUI package manager interface running, and then try to run apt-get to install/update packages. I kept getting the same problem with my Ubuntu laptop - doh!

If you can't find the other process somewhere,

You may need to do

ps aux |grep apt

and kill the process
