Google Music "could not identify your computer" in ubuntu

When I was trying to get Google Music working on my Ubuntu install, I was getting the following error:

Thanks, helpful, Google

On my motherboard, I have two ethernet ports. Doing an ifconfig, I saw something weird with my MAC addresses.

Two bits if you can see what's weird

I’m only using eth1, but you can see that both of the ethernet ports are reporting the same MAC address of aa:00:04:00:0a:04. I found this post detailing that the DECNet tools is what causes the MAC address to be the same. To remove them, run the following:

$ sudo apt-get remove dnet-common libdnet

Reboot, and running ifconfig will show your ethernet ports mapped to their correct MAC address. Now you should not have any problems running Google Music!
