Comment 129 for bug 1640978

This bug was fixed in the package python-letsencrypt - 0.7.0-0ubuntu0.16.04.1

---------------
python-letsencrypt (0.7.0-0ubuntu0.16.04.1) xenial; urgency=medium

  [ Robie Basak ]
  * This update is part of the set of major updates moving Let's
    Encrypt/Certbot to version 0.23 in 16.04 in order to allow it to
    continue working following the general shutdown of TLS-SNI-01
    validation (LP: #1640978).
  * The new source package python-certbot takes over this package's
    functions, with binary packages certbot, python-certbot and
    python-certbot-doc taking over respectively.
  * The following two functional changes are additionally made:
    - Log rotation is switched to logrotate via
      /etc/logrotate.d/certbot, and /etc/letsencrypt/cli.ini is
      introduced to disable internal log rotation to avoid collision.
    - Automatic renewal is enabled via the certbot.timer and
      certbot.service systemd units.

  [ Michael Casadevall ]
  * Replace python-letsencrypt with a compatibility shim
