If you run what I wrote on Sun, 2017-04-16 at 17:37 +0200...

... you prevent /usr/bin/tracker to get reinstalled by an upgrade.

You also could use "org" or anything else instead of "backup", e.g.

  sudo dpkg-divert --add --rename --divert /usr/bin/tracker.org /usr/bin/tracker

If you can't uninstall the package containing /usr/bin/tracker and you shouldn't
use a workaround like dpkg-divert, the next upgrade of the package containing
/usr/bin/tracker will reinstall /usr/bin/tracker.
