A colleague had the same problems (at the same day... :) and after some 
time we found that in the process of the update to 16.04, Ubuntu/apt-get 
decided to de-install the package "scdaemon"!

So as the scdaemon is mandatory for gnupg card usage and ssh auth 
access, he re-installed it and afterwards he was back to business.

But keep in mind: He had a working ssh/gpg/smart card setup *before* 
starting the update to 16.04
and this setup was also not quite intuitive either. :-)
