I'm following a tutorial that says I need to run sudo apt-get update and then install a whole bunch of packages. All of them work, except policykit. It gives me Unable to locate package policykit. Is there something I need to do to help ubuntu find it. I'm new to ubuntu so not sure how this works, or if I need to put the ubuntu installation CD for this to work or what.

A general suggestion:

Whenever you are in such situation, try the following command to locate the package:

apt-cache search packagename

And after that try to install the packgae which reads as packagename-dev or libpackage name

suod apt-get install packagename-dev

The package you are looking for is installed using:

sudo apt-get install policykit-1

You can search for packages using:

apt-cache search policykit
