Disable the repository which provides QGIS 2.16, it hasn't been built 
with the ubuntugis-unstable dependencies.

qgis from ubuntugis-unstable has the correct dependencies, but is still 
at version 2.14.3.

You need libgeos-c1v5 from ubuntugis-unstable, not libgeos-c1 from the 
ubuntu repository.

aptitude's first suggestion is usually not very good, but the second 
tends to be better, so chose 'no' instead of 'quit' to get the second 
option.

Or just use apt-get instead of aptitude.

Kind Regards,
