OK, @postlund. Thanks. Let’s try to get a short guide for this.
This a short description of what I tried (unsuccessfully). Obviously, my little knowledge is insufficient.
I run Home Assistant in a virtaulenv inside a FreeNas jail (OS FreeBSD 11.3-RELEASE-p7).
I used the set-up from the excellent guide from @troy.
OpenSSL version is 1.0.2. The OS can not be upgraded, because the one in the jail can not be greater than the base OS of the FreeNas system. FreeNas is always behind FreeBSD.
So, I followed the recommendations in https://www.ixsystems.com/community/threads/openssl-update-to-1-1-1.76814/post-535033:
Install OpenSSL 1.1.1 with pkg install openssl and then reinstall the software using the option DEFAULT_VERSIONS+=ssl=openssl111 in /etc/make.conf.
I don’t really know what needs to be installed again to make openssl1.1.1 work in Home Assistant.
I tried this: install again python3.7, create a new virtualenv and re-install Home Assistant in it.
HA starts, but reports problems with several integrations: cloud, mobile_app, alexa and broadlink. In the logs, the common entry is:
Unable to import component: /srv/homeassistant/lib/python3.7/site-packages/cryptography/hazmat/bindings/_openssl.abi3.so: Undefined symbol “OPENSSL_no_config”.
If trying to set-up the AppleTV integration with HACS, I get the same error:
Error occurred loading configuration flow for integration apple_tv: /srv/homeassistant/lib/python3.7/site-packages/cryptography/hazmat/bindings/_openssl.abi3.so: Undefined symbol “OPENSSL_no_config”.
All help is welcomed.
