New user: Frustrated - No Supervisor connectivity, delaying version fetch

I’m a brand new user. I literally just built a Raspberry Pi 5 and had Home Assistant installed on its m.2 SSD. It appeared to build as expected and it eventually dropped me at the screen telling me my URL. But when I go to connect via my iPhone app, it sends me to the “Preparing Home Assistant” page with “This may take 20 minutes or more” underneath. When I click “Show Details,” I’m seeing nothing but errors, primarily these:

(MainThread)
[supervisor.homeassistant.core] Error on Home Assistant installation. Retrying in 30 sec
(MainThread)
[supervisor.updater] No Supervisor connectivity, delaying version fetch

But when I go to update it via the CLI, it tells me there are no updates so that suggests it’s not an Internet connectivity problem.

Please try to convince me I’m not too stupid to do this project. I’ve been excited for weeks to get it up and running and I’m already dead in the water 10 minutes in.

Patience grasshopper…
You are ten minutes into a 20 minute process, and somebody may have omitted a progress bar in the shiny new code?
Chill.
Have a beer and come back in an hour!

Same errors over and over and over again.

Welcome back. How was the beer? Time to look in the error logs for more clues.
Fixing broken things is the shortest path to full understanding of how it works.

I posted the logs in the original post. That’s what it’s repeating over and over again.

Other processes may need to complete before connectivity is achieved is all one line quote from the log shows me.

Did you download the very latest software version to build your system with? If you did, there should not be any updates to download. What mechanism did you use to download it and configure it for initial use? Is it the correct version for your Raspi? How did you get it onto your M2 drive? Do you have a SD Card still plugged in while it is starting?

Is there anything different about your environment compared to a standard system? Do you have time to try a SD Card HomeAssistant install, and then transfer it to your M2 drive after it is working?

Is your internet connection to the Raspberry Pi actually working? Try a standard Raspi OS install and see if it connects via the browser, and then you will have big confidence the issue is software or configuration, rather than hardware and external factors outside your control.

Process of elimination: Cross off the things it cannot be, and the underlying cause will eventually become obvious.

Check that your router is allowing both NTP through and that you have access to all the urls listed on the troubleshooting page.

Can you browse to your HA url with a standard desktop browser? Post a screenshot of what you see there.

Yes, until NTP processes can connect and update the time and date on your Pi, any version comparisons based on dates are probably going to fail. Trying a standard Raspi OS install that functions properly and displays the correct date locally will eliminate that from the problem checklist.

I has a similar issue, I decided to try and restart the rpi from cmdline by typing supervisor restart - but this didnt restart the rpi but it seemed to restart the supervisor instead - after that things sprung into action for me. Not sure if this is a coincidence or not

Have you fixed the problem?
I have the exact same issue.

What happens when you try the latest (revised) version?

I received this message

By connecting the Wi-Fi directly from the Rbi4, I received this message

Looks like your WiFi credentials have not been defined.
Please describe what process you followed to obtain your HomeAssistant image file to download and what steps you took before you started your . Raspberry Pi for the first time to get it onto the SSD? A link to the relevant web page would be sufficient.

I used the Raspberry Pi Mac OS application and the HA 16.3 firmware, which I copied directly to an M.2 SSD. Then I connected the screen and keyboard to the Raspberry Pi to select the Wi-Fi network and password.

I should mention that I live in Ivory Coast. but the equipment was purchased in France

Ii note the new imager was just released by Raspberry Pi. Any bug reports in the forums for it? English or French versions?

If you are certain that the WiFi network credentials were correctly entered and saved (please go back and check them carefully), there may be a problem with the Raspberry Pi imager software not writing the start-up configuration file correctly to the correct drive, or the HomeAssistant OS installation routines not finding it as it is unpacking the startup installation routines.

For purposes of troubleshooting can you try the following:
Does the process work when using a SD Card instead of the M2 SSD?
Does it work any different using the older version of the imager software? Does it work with the standard Raspberry Pi software instead of the HomeAssistant one (just to see if it actually writes the credentials out correctly)

I see you using your iPhone as a WiFi hotspot. Does the phone show a connection and IP address from the Raspberry Pi during the installation process? (I hope you have a large data allowance too as this process is quite data thirsty, and downloading multiple OS images may get a little exoensive)

How have you connected your M2 SSD to the Mac?

Update: I found this: [BUG]: SSH Public Key Authentication Casus Customisations (Hostname, User, Locate) to Fail to Apply in Imager v2.0.0 · Issue #1320 · raspberrypi/rpi-imager · GitHub and this [BUG]:Enabling SSH does not enable SSH · Issue #1242 · raspberrypi/rpi-imager · GitHub in the Raspberry Pi Imaging GitHub repository bug reports - maybe the problem lies with the actual image being downloaded or the way it is written by the imager and not HomeAssistant at all?

Assumption the imager software is working correctly may be incorrect. Yikes!

At least you aren’t being condescending and ridiculous here.

Hi!

I have the very same issue:

yesterday tried to install the HAOS using the official rpi imager + sd card (new and original) + rpi4 (with original psu).

The image was created succesfully, the rpi boots up (green led flashes for about a minute), the rpi is accessible via browser, and when I click on the “show details” it keeps cycling the same error messages every 30 seconds.

I tried to re build the image on the sd card, tried with 3 different routers, 2 different ethernet cables, no luck.

Did you solved the problem?
