Same issue here, also in a reboot loop after the update.

Same issue here… And dont have time to recover a snapshot, any idea??
May I ask about the long term statistics? I’ve checked Statistics and Recorder in Docs now. The default purge_keep_days for Recorder is still 10 days. Shouldn’t this be somehow updated? If I have this set to 7 days should I remove it to keep the long term statistics? Or how is this handled? Thanks.

This is the second time in a year that an updated bricked my HA smart home. More testing is needed before releasing, a lot of people rely on HA for a lot of day-to-day functions.

How can I access to the backups now?
remove sd card put it into a pc and browse the files.
I think your use of “brick” is exaggerated here. At the most, your HA core might be crashing?
“Brick” implies the whole device is dead.
You should have many ways to access your files in this situation. Samba, SSH, FTP add-ons, etc.

I only have like 30 seg before the device restars completely…
His terminology might be incorrect but I don’t believe a brand new release stopping your HA instance from working is appropriate.
If you don’t have Samba etc on by default you don’t have many options left other than starting over and restoring from backup.
If stability is your main goal, I’d never recommend upgrading any software a couple hours after release. Unless it’s to patch security vulnerabilities. There is a reason why businesses tend to opt for semi-annual, ltsb etc. Its almost impossible to release software without some kind of bug, especially on the scale and complexity of this sort of project. Hopefully you get the issue sorted =)

Not to sound too harsh but, never install .0 versions on important systems.
That said, perhaps HA should promote an early release group for broader beta testing.

This isn’t going to help immediately but there is a Google Drive add-on you can get by custom repository. It copies snapshots/backups to your Google Drive for this exact event. There are dropbox ones etc too.

There’s a breaking changes list for every release and we have no idea if that is in play here. Terminology is at least helpful.
And yes, Samba, ssh, any of the add-ons which provide access for when you inevitably lose the frontend are a given. You have to install and run something to make this a complete system.

There are a bunch of these in my Supervisor log after an update:

The funny thing is that I don’t have some of these addons installed - like deCONZ and UniFi
There is a github issue open here: 2021.9.0 - causing my Pi3 to restart over & over ? · Issue #55541 · home-assistant/core · GitHub
I’ve tried to replicate the issue with a fresh RPi3 install. Unfortunately, everything worked great and I wasn’t able to make the boot loop happen.
Is it safe to upgrade on a RPI4 w/ SSD ? In other words, are all the prior boot-loop reports installs on RPI3?
Ok that’s a lesson, I thought I was safe on the stable version because of some beta testing before the release but of course I wasn’t.
I’m lucky I use my automations for fun and not for work

None of those help if the machine is in an endless bootloop.

That is expected and OK. They are in your addon store, hence the warning. Ignore.
