The suggested workaround is now impractical because it has negative consequences.
The workaround suggests modifying Supervisor’s source code. Since Supervisor version 2021.05.3 it detects changes to its source code and marks your instance as Unsupported and Unhealthy (and then you can’t add/update Add-Ons or update Home Assistant).
There is a command line option to disable checking for source code modifications. If disabled, it simply flags your instance as Unsupported. However, in version 2021.05.4 that option broke. Even if disabled, it still marks the instance as Unsupported and Unhealthy. I reported the bug as an issue a week ago (and there has been no reply yet).
+1 for this. I find it absurd that we’re resorting to blocking outgoing connections, this isn’t a chinese ip camera.
The pros have already been discussed thoroughly. If there are reasons to keep this feature that we don’t know about it would be great to hear them so we can understand why things work like they do.
Is this feature documented somewhere? Couldn’t find it.
My HomeAssistant install keeps breaking because Supervisor gets updated, but core does not. I end up with a broken system on reboot, which I inevitably find out about when I’m trying to go to bed and wondering why lights won’t turn off.
Having to implement blocks at DNS level to prevent a piece of open-source software from updating is beyond insane.
I just wanted to chime in. My HA installation just broke because of the Supervisor happily updating and the rest of the system kept on a stable known-to-work version. I finally decided to upgrade, and I could not even create a backup (!). Or more, precisely, a backup was created but it was not being listed for download.
When trying to figure out what was wrong, I noticed the following:
For God’s sake, how can a system update itself into an unsupported installation ?
EDIT: just for reference, this is not something like 3-year-old setup left unattended. It was installed from scratch 10 months ago. And now I could not backup the config without an upgrade of the whole system. This is ridiculous.
For what is worth, I am thinking of nuking this setup and installing HA Container where I can control what is updated and when. Any auto-updating system should be relegated to testing/development usage and not production, especially one that integrates with real-world hardware.
Could you elaborate on that? I cannot envision any possible disaster resulting from not updating, it’s usually the opposite. Updates break things, I know that because I write software for a living.
The update I did today broke my tuya integration, my looko2 integration and needed re-auth from netatmo. Now I need to install some chinese app just to operate my thermostat. Are you saying that people click “update” every month and have fun resolving the incompatibility issues on a regular basis?
Each update can introduce a small breaking change or two. Not an issue if you deal with it at the time. One update a month. If the breaking change affects you it is almost always a simple fix.
If you let the updates accumulate so that you have to deal with 10 months of breaking changes at once when you have to update due to a vital security patch or OS update, you are going to have a very bad time.
I ended up blocking version.home-assistant.io in DNS. I have subscribed to receive release notifications for each add on as well as core and supervisor so when there is an update I read the release notes, take a full backup, remove the DNS block update and put the DNS block back on. It’s a pain but at least I have an option to update as and when I can. Rather than this happening when I’m away and losing my whole setup. By the way that did happen already!
Yes. Essentially blocking this URL prevents HA from checking and downloading new versions therefore it is not able to update supervisor. This also stops all add ons from downloading their updates which is not really useful as add ons can be prevented from auto update.
I can confirm that this blocks add ons updates on my system as well as supervisor and core. It may not block downloading the add on updates, they all come from github… but it certainly stops add ons, supervisor and core from checking for updates and showing that an update is available hence at least core and supervisor won’t do an auto update.
