package docker.io is broken

[Dimitri John Ledkov]

It says right in the installation log why it is incompatible with your system:

"""
The aufs storage-driver is no longer supported.
Please ensure that none of your containers are
using the aufs storage driver, remove the directory
/var/lib/docker/aufs and try again.
"""

The package prevents breaking your containers which are still
potentially using obsolete storage driver. Make sure you don't have
any containers using obsolete storage driver, and remove the directory
as directed above (which may DESTROY data). And try again.

Dimitri.
