Upgrading from an ancient version of Home Assistant
(images2.imgbox.com)
Home Assistant is open source home automation that puts local control and privacy first. Powered by a worldwide community of tinkerers and DIY enthusiasts. Perfect to run on a Raspberry Pi or a local server. Available for free at home-assistant.io
Do a backup first, if the update does go south the backup might apply to a new install
That's what I just did with pihole v6 lol.
Updated, internet went down and WebUI bork. Uninstalled, wiped config, reinstalled, restored backup.
Same for me but I managed to rescue the existing installation, but unfortunately my reverse proxy for the web interface doesn't work anymore.

On the plus side, if the update works there is a good automated backup system now, so it won't be an issue again, I suppose.
