Snapshot "Unknown error, see supervisor"

Good morning,

I’ve tried this morning to make an snapshop, but after a minute i get the following error message:
18-11-_2020_07-46-56

but whenI refresh the page I can see the created Snapshot.

regards Tim

Look in the supervisor logs for any errors.

Try downloading the snapshot and opening it with a file compression tool, do you see everything you should have backed up?

this is my logfile:

When I exclude the addons, everything is fine.
Also when I download the Snapshot, it looks fine.

Try a full reboot (Supervisor / System / Host System tab / Shutdown button).

If it still happens after that you might have to log an issue here: https://github.com/home-assistant/supervisor/issues

I do remember I used to get errors when creating very large snapshots but not what the actual errors were.

You could always create a partial snapshot. You don’t really need to back up these:

Mosquitto - just save the configuration in a text file off system somewhere. Paste it back in if you ever have to reinstall it.

ESPHome - just save the configuration in a text file off system somewhere. Paste it back in if you ever have to reinstall it. All the device files are backed up in your config folder.

Samba - just save the configuration in a text file off system somewhere. Paste it back in if you ever have to reinstall it.

Configurator - can’t really comment on this one as I don’t use it. but I suspect you would be ok with just saving the configuration.

Going to test it tonight when Im back home.
I’ve just tried it over Nabu Casa, perhaps this is the fault. With Nabu Casa I sometimes get an timeout.
Would you recoment to make a clean install or just leave it like this ?

The snapshot runs locally on your home assistant server. It has nothing to do with Nabu Casa.

That’s way too drastic. No need for a reinstall at all.

Just a little update.

If I exclude the share and media folder the snapshot is fine.
Thats ok for me, i dont need the share an media folder in my backup

I am having this issue also. I can not make or restore a snapshot. Error on attempting to restore is ‘‘Error: Unknown error, see supervisor’’. Log records ‘HomeAssistantCore.update’ blocked from execution, system is not healthy" when I attempt to upgrade to latest H/A Supervisor version 0.118.2 from 0.118.0.Any suggestions?

Yes, same problem here. I noticed over the last few days since updating to version 0.118.0, that I cannot update the core. As well my daily snapshots have not happened for the same time period.

I see:
Update Available
Home Assistant Core 0.118.3
You are currently running version 0.118.0

When I select I get the next box:
Update Home Assistant Core
Are you sure you want to update Home Assistant Core to version 0.118.3?
and when I select that button, nothing happens.

When I look in the log I see:
WARNING (MainThread) [supervisor.jobs] ‘HomeAssistantCore.update’ blocked from execution, system is not healthy
WARNING (MainThread) [supervisor.jobs] ‘SnapshotManager.do_snapshot_full’ blocked from execution, system is not healthy

I also tried to install an Add-On, and then I see:
WARNING (MainThread) [supervisor.jobs] ‘AddonManager.install’ blocked from execution, system is not healthy

Host System is an Intel Nuc
Operating System Ubuntu 20.04.1 LTS
Docker version 19.03.13
Running Nabu Casa

Supervisor
Version 2020.11.2
Newest Version 2020.11.0
Channel stable
You are running an unsupported installation.

I’ve done multiple restarts of HA, full reboots of host system, and tried through VNC and the iOS apps. No joy.

Is it possible that the update to 0.118.0 caused an error?
I recognize Supervisor is not supported for Ubuntu 20.04.1 LTS. Is it even possible to not run Supervisor, and should I remove it somehow? How does one figure out why the “system is not healthy”? The “More Info” link just takes me to the log where I see the above entries.

Is there a way to run updates manually?

Thanks!

there’s an open ISSUE

Should be fixed with latest Supervisor 2020.11.3
