_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`
