Can someone please help me understand how to fix the following error in Ubuntu's Software Manager? I am running Ubuntu 10.04.

I was trying to install Adobe's Flash Plug-in for Firefox when I got an error message that says:

Software index is broken This is a major failure of your software management system. Please check for broken packages with synaptic, check the file permissions and correctness of the file '/etc/apt/sources.list' and reload the software information with: 'sudo apt-get update' and 'sudo apt-get install -f'.

So, I ran the two commands mentioned above and my output is below:

Try sudo apt-get remove mysql-cluster-client (if you don't need that for now), and then retry the sudo apt-get install -f
