The ubuntu package is a couple releases out of date even in Xenial and we're hitting some random crashes with the version we're running. Hopefully a newer version will fix it. Switching to the PPA will get us the same version slated for inclusion in Ubuntu 18.04 LTS (Bionic) until we have an opportunity to upgrade the server.
