Last week that I upgraded to Ubuntu 8.10 I noticed that my AWN Dock was gone, but I found out how to get it to work again, here is check it out it is easy and quick.
1. First remove any AWN packages or repos if there is any.
2.- Go to System>Administration>Synaptic Package Manager and on the search bar type “awn” and thats it. To find AWN Dock go to Applications>Accesories>Avant Windows Manger.
Hope this works, Enjoy it! Please tell me let me know if this work.
