The UbuntuOne link that adds the PPA is a package, not an AptURL link:
https://media.ubuntuone.com/media/files/ubuntuone-jaunty-ppa.deb
Then there's an AptURL link below that to install the client package.
apt://ubuntuone-client?refresh=yes
But AptURL has the functionality to do both steps in one, if I understand correctly; it's just disabled by default. I don't know why. Installing random debs seems more dangerous and less reliable than installing PPAs.
