What exactly do you want to do? For package management, you can use apt: Code: apt-cache search searchstring to search for packages, Code: apt-get install package to install a package, Code: apt-get remove package to remove a package, etc. I don't know if there's a similar tool to yast... But I'd always go with the defaults for a distribution, and on Ubuntu it's apt. That way you''re less likely to mess up your system.
