Can not install on Debian Stretch (Backports)

[slokhorst]

Hi all, I’m having trouble installing Certbot following this guide.

I’ve enable the backports repository as instructed, but when I run apt-get install certbot -t stretch-backports I get the following:

Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 certbot : Depends: python-certbot (= 0.19.0-1~bpo9+1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

It looks very similar to this previous topic.

Am I doing something wrong or is there a problem with the Debian repository again?

Same problem for me ! Debian 9 with Apache.

Seems stretch-backports really does have version 0.21.1 of python-acme but only 0.19.0 of Certbot.

https://packages.debian.org/source/stretch-backports/python-acme
https://packages.debian.org/source/stretch-backports/python-certbot
https://packages.debian.org/source/stretch-backports/python-certbot-apache
https://packages.debian.org/source/stretch-backports/python-certbot-nginx

Maybe today is just bad timing? Or version 0.21.1 of Certbot got delayed? I dunno.

[Patches]

The missing packages are on the way so this should be fixed soon.

In the meantime, you can manually download and install the old version of python-acme and then install the rest of certbot through apt:

wget https://cdn-aws.deb.debian.org/debian/pool/main/p/python-acme/python-acme_0.19.0-1~bpo9+1_all.deb
sudo dpkg -i python-acme_0.19.0-1~bpo9+1_all.deb
sudo apt -t stretch-backports install -f
sudo apt -t stretch-backports install python-certbot-apache
