The ppa name is :

ppa:gwibber-daily/ppa

Adding the PPA to Ubuntu 9.10 (Karmic) and later

If you’re using the most recent version of Ubuntu (or any version from Ubuntu 9.10 onwards), you can add a PPA to your system with a single line in your terminal.

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[/code]

 
 
Step 2: Open a terminal and enter:
 
sudo add-apt-repository ppa:user/ppa-name[/code]

 
Replace 
ppa:user/ppa-name[/code] with the PPA's location that you noted above.

 
 

 
 
Your system will now fetch the PPA's key. This enables your Ubuntu system to verify that the packages in the PPA have not been interfered with since they were built.
 
 

 
 
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[/code]

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