Comment 6 for bug 58560

This is a mirroring problem, and should not be rejected... though I'm personally not sure how to contact the mirror administrator in question.

The packages without the ~dapper1 part are not the correct packages; those are for Edgy.

For now, I recommend you switching to a non au mirror.
