Then copy /etc/apt/sources.list to /etc/apt/sources.list.d/sources-natty.list replacing all occurrences of 'oneiric' by 'natty'
Finally,
sudo apt-get update # if there are errors, comment out the appropriate lines in sources-natty.list
sudo apt-get --purge remove rhythmbox
sudo apt-get --purge autoremove
sudo apt-get install rhythmbox
Not sure when we'll see the fixed package come out in oneiric but until then, one solution is to pin rhythmbox back to the natty version:
To do so, create the file /etc/apt/ preferences. d/rhythmbox- pin containing:
Package: rhythmbox
Pin: release n=natty
Pin-Priority: 1001
Then copy /etc/apt/ sources. list to /etc/apt/ sources. list.d/ sources- natty.list replacing all occurrences of 'oneiric' by 'natty'
Finally,
sudo apt-get update # if there are errors, comment out the appropriate lines in sources-natty.list
sudo apt-get --purge remove rhythmbox
sudo apt-get --purge autoremove
sudo apt-get install rhythmbox
Enjoy.
