A PPA is one place for apt-get to fetch packages from.
If you find apt-get update gives you 3.00, 3.01, etc., soon after
they're released, then you pulling their packages from somewhere other
than a stable Ubuntu 2016-10, etc., that wouldn't update much once
released;  that might be a PPA you've told it about in the past.
