Status changed to 'Confirmed' because the bug affects multiple users.

Looks like a circular dependency that has nothing to do with ca-certificates:

dpkg: cycle found while processing triggers:
 chain of packages whose triggers are or may be responsible:
  gconf2 -> gconf2
 packages' pending triggers which are or may be unresolvable:
  ca-certificates: update-ca-certificates

ca-certificates postinst is not run because it waits for the dpkg problem to be solved first.

ca-certificates postinst is not run because it waits for the other packages to be taken care of.

New distro package 16.04 LTS cancelled and not installed. Will try again at later time.
