Comment 130 for bug 1640978

This bug was fixed in the package python-acme - 0.22.2-1ubuntu0.1~16.04.1

---------------
python-acme (0.22.2-1ubuntu0.1~16.04.1) 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).
  * This package is a dependency of Certbot and using the 0.22 version
    in Bionic is the most straightforward backport choice. Version 0.22
    of this package is sufficient to fulfil the dependency requirement
    for Certbot 0.23.

  [ Michael Casadevall ]
  * Backport to Xenial for LE change
