Step 2: Use the Display sources.list entries drop-down box to select the version of Ubuntu you're using.
Step 3: You'll see that the text-box directly below reads something like this:
deb http://ppa.launchpad.net/adilson/experimental/ubuntu maverick main
deb-src http://ppa.launchpad.net/adilson/experimental/ubuntu maverick main

Copy those lines.
Step 4: Open a terminal and type:
sudo gedit /etc/apt/sources.list
This will open a text editor containing the list of archives that your system is currently using. Scroll to the bottom of the file and paste the lines you copied in the step above.
Save the file and exit the text editor.
Step 5: Back on the PPA's overview page, look for the Signing key heading. You'll see something like:
1024R/27B81625 (http://keyserver.ubuntu.com:11371/pks/lookup?search=0x50AB22E78528C1C33363EE08D715961D27 B81625&op=index)
Copy the portion after the slash but not including the help link; e.g. just 27B81625 .
Step 6: Now you need to add that key to your system so Ubuntu can verify the packages from the PPA. In your terminal, enter:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 27B81625
This will now pull down the PPA's key and add it to your system.
Step 7: 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
sudo apt-get install gyachi
