[Banshee-List] Strange Problem During Build-Dep Banshee

[David Wen Riccardi-Zhu <dwriccardizhu gmail com>]

Hello all,

I am trying to follow this guide http://doc.gwos.org/index.php/Banshee_and_plugins to install Banshee and eventually most plugins.

At step #4, sudo apt-get build-dep banshee I get the following:

Reading package lists... Done
Building dependency tree 
Reading state information... Done
E: Could not open file /var/lib/apt/lists/xgl.compiz.info_dists_dapper_main_source_Sources - open (2 No such file or directory)

I have no idea what this is... how do I fix this?
