I get the following errors as I execute $sudo apt-get update
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?
What's causing this?
Also, earlier, I removed Openoffice3.0 using Synaptic in order to upgrade to 3.1. I might have accidently removed some dependencies. How would I check if all dependencies are there and should I execute the following command to get them back?:
sudo apt-get install -f
Thank you for your help.
