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. A stanard Raspi OS install that functions properly and displays the correct date locally will eliminate that from the problem checklist.
