The system is now reporting that I am running an Unsupported Installation. It is also up-to-date. I am running supervisor mode on a VM and it said it was supported last time I looked. I click to learn more and it sends me to Ignored content trust - Home Assistant
When I run the command ha supervisor options --content-trust I get the error “Error: Unknown Flag: --content-trust”.
Don’t have a clue, but since the latest supervisor update you do need os-agent installed. Did you install os-agent ?
Thanks for the contribution! I’ve been largely inactive on notary since I left Docker ~18 months ago but I’ll see if I can get a review on your PR today. Happy to see somebody using it.
Thank you Francis. This was the problem. I had just been updating through the interface and it had never notified me that I needed manually install os-agent.
I followed the steps here and the issue is resolved: https://github.com/home-assistant/os-agent
Hi, I think I have the same problem : Supervised version on VM.
I have just upgraded supervisor to supervisor-2021.09.4 with the same message.
I have tried to install OS Agent (downloaded os-agent in BackUp directory) but I have an error message :
Command not found ?
Thanks for your help.
Try without sudo
Are you able to login directly to the host console? That is where I installed mine.
Host console ? With Putty ? It’s not the same ?
I too have started getting this flag (running Home Assistant Supervised on debian), but when I go to install the 1.2.0 linux x86/64 OS Agent deb, it fails due to udisks2 not being installed, which then has quite a few more dependencies.
I then spotted that the official guide now mentions Debian 11 rather than Debian 10, so should I sort out the udisks issue or just do a whole new install?
Could this not be in an apt repo/ppa that we could add to our systems? Then it would get updated when a new version is published and not just die on the vine.
I will forget to update this… unless something breaks which will just be another annoyance.
I am on debian 11 but had similar experience.
sudo dpkg -i os-agent_1.2.0_linux_armv7.deb
sudo apt install udisks2
sudo apt --fix-broken install
Seems to have done the trick
Thanks - I got it working with sudo apt-get install -f then I had to reboot to get HA to remove the flag. Think I’ll leave off a Debian 11 install for now.
In 3 months Debian 10 will be unsupported.
ha supervisor options --content-trust
Error: unknown flag: --content-trust
Still get that after install and reboot but the other command on https://github.com/home-assistant/os-agent
gdbus introspect --system --dest io.hass.os --object-path /io/hass/os
worked.
And the system page doesn’t have the warning about os-agent.
Great, that works for me, after a complete reboot ! (I have done the first sudo at the end, not first). Tanks 
I have Debian 10. I guess we have to go to 11 ? Is it cumbersome ?

Thanks - Debian 11 upgrade complete.
