If you want in one command and not use Software source ticking then in terminal put:

sudo add-apt-repository universe

On older versions of Ubuntu, you might have to use a full source line:

sudo add-apt-repository "deb $(lsb_release -sc) universe"

To enable all Ubuntu software (main universe restricted multiverse) repositories use

sudo add-apt-repository "deb $(lsb_release -sc) main universe restricted multiverse"

you can add also partner repository with different link (see difference is ubuntu to canonical)

sudo add-apt-repository "deb $(lsb_release -sc) partner"

Then update the package list:

sudo apt-get update

p.s.

$(lsb_release -sc) checks your Ubuntu version and puts its name in the source link. Since 12.04 is called precise, you can test in a terminal that lsb_release -sc gives precise. That adds the precise name of your Ubuntu release in Software sources. Wrong word and nothing will work.

For all differences in repositories read

First, open software center. Click on 'edit' and then 'software sources' to open the software sources window. Once that is open, check the box that says, "Community-maintained free and open-source software (universe)."

Now, all the universe packages should show up in software center just like all the other ones.
