Please note though, that since AWN hasn't been updated in a long time, some applets won't work!
Install Avant Window Navigator In Ubuntu 13.04 Or 12.10
To add the main WebUpd8 PPA and install Avant Window Navigator in Ubuntu 13.04 Raring Ringtail or 12.10 Quantal Quetzal, use the following commands:
sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install avant-window-navigator
For older Ubuntu versions, you don't need to add our PPA since AWN is available in the official repositories so you can install it via Ubuntu Software Center.
To install it, see our previous DockBarX article: DockBarX Sees New Release, Now Available For MATE Desktop Too
