+_If you are using [Hass.io](https://www.home-assistant.io/hassio/installation/), [Docker](https://www.home-assistant.io/docs/installation/docker/) or a distro based on Debian Buster this does not apply to you._
+
+After upgrading to Home Assistant version 0.96.0, some users started seeing errors like this:
+
+```text
+ImportError: /usr/lib/arm-linux-gnueabihf/libssl.so.1.1: version `OPENSSL_1_1_1' not found (required by /srv/homeassistant/lib/python3.7/site-packages/cryptography/hazmat/bindings/_openssl.abi3.so
+```
+
+And all integrations that communicated with SSL (https) stopped working.
+
+This applies if you have one of these installations with a manual installation or with Hassbian:
+
+- Raspbian Jessie
+- Raspbian Stretch
+
+The reason for this, is the way piwheels determines the OS version you have by looking at the Python version that is in use.
+
+[@frenck](https://github.com/frenck) added a writeup of the issue and potential solutions to [this issue](https://github.com/home-assistant/hassbian-scripts/issues/307#issuecomment-512963048).
+
+There are two potential solutions for this issue, where option 1 are considered the best of them.
+
+## Option 1
+
+Upgrade your distribution to Debian Buster.
+
+**NB!: This option will upgrade your entire system and _might_ negatively affect other things you might have running.**
+
+Before you continue with this, you should make sure that you have a recent backup of your system.
+
+### Steps
+
+1. Change `stretch` or `jessie` to `buster` in these files:
+   - `/etc/apt/sources.list`
+   - `/etc/apt/sources.list.d/raspi.list`
+   - `/etc/apt/sources.list.d/hassbian.list`
+2. Run `sudo apt-get update`
+3. Run `sudo apt-get -y dist-upgrade`
+4. Run `sudo reboot`
+
+## Option 2
+
+Disable piwheels prebuilt packages.
+
+This option is a faster method initially, but it has the huge drawback of having to compile the packages locally.
+You should only use this option if you run other things on your system that will not work if you use the first option.
+
+### Steps
+
+1. edit `/etc/pip.conf` and comment out the line containing piwheels, like this:
+
+      ```text
+      [global]
+      # extra-index-url=https://www.piwheels.org/simple
+      ```
+
+2. Run `source /srv/homeassistant/bin/activate`
+3. Run `pip uninstall cryptography`
+4. Run `pip install --no-cache cryptography==2.7`
+5. Run `deactivate`
