There was an article a few weeks ago about the newer iPods and how Apple changed the crypto hash for them which made them incompatible with current versions of Linux software. Well, there has been a lot of work to make them functional under Linux, and now here's a quick How-To on getting these fixes installed on your Gutsy installation.
- Go and download the libgpod and rhythmbox packages from ftp://188.8.131.52/packages/gutsy/
- Install the python-mutage package via apt 'sudo aptitude install python-mutagen'
- Use 'sudo dpkg -i /path/to/debs/*.deb' to install each of these packages.
- Now, you should be able to fire up RhythmBox and sync your iPod and have it work without the dreaded "No Music" message showing up.
