PPA

Step 1

On the PPA's overview page, look for the heading that reads Adding this PPA to your system. Make a note of the PPA's location, which looks like:

ppa:gwibber-daily/ppa

Step 2

Open a terminal and enter:

sudo add-apt-repository ppa:user/ppa-name

Step 3

Now, as a one-off, you should tell your system to pull down the latest list of software from each archive it knows about, including the PPA you just added:

sudo apt-get update

Now you're ready to start installing software from the PPA!

Per Skript
