parcimonie binary package in Ubuntu Bionic ppc64el

 parcimonie is a daemon that slowly refreshes a gpg public keyring
 from a keyserver.
 .
 Its refreshes one OpenPGP key at a time; between every key update,
 parcimonie sleeps a random amount of time, long enough for the
 previously used Tor circuit to expire.
 .
 This process is meant to make it hard for an attacker to correlate
 the multiple performed key update operations.
 .
 See the included design document to learn more about the threat
 and risk models parcimonie attempts to help coping with.
 .
 parcimonie also ships a desktop applet that allows one to monitor
 the background daemon's activities with a graphical user interface.
