Beginning with brownouts in January 2021, and ending with a total shutdown in June 2021, the Let's Encrypt APIs will become unavailable. To prevent users having disruptions to their certificate renewals, this update backports the switch over to the ACMEv2 API.

For Debian 9 stretch, this problem has been fixed in version 0.28.0-1~deb9u3.

We recommend that you upgrade your python-certbot packages.

For the detailed security status of python-certbot please refer to its security tracker page at: [link moved to references]
