Hi,
Someone over in the Beaglebone Group tried switching to the new repositories, and it worked OK for him: https://groups.google.com/d/msg/beaglebone/Z2ntCz6r934/FUByJoD6PLcJ
I’m not very knowledgeable about this sort of thing, but I would have guessed that there would be conflicts between the old image’s kernel and the kernel module updates in the new repositories.
