Raspberry pi shows wrong time and cannot set up homeassistant

Installation

i need help i have multiple times tryied reinstalling home assistant but to be with the same issue this is what it keeps saying 2025-06-25 22:21:37.231 INFO (MainThread) [supervisor.updater] No Supervisor connectivity, delaying version fetch
2025-06-25 22:21:37.231 WARNING (MainThread) [supervisor.homeassistant.core] Error on Home Assistant installation. Retrying in 30sec by the way it is the 9 of september not august 25

The hint is the connectivity. It probably cannot connect to update the time, and download data needed to complete the install.

What platform are you installing on? Physical as well as logical?

Where is it getting the June date from? Where have you got your install files from? Are they the latest available?

3

Why do you think this has anything to do with the date? Sure, it’s wrong, but the error messages aren’t referencing a date issue.

Also, wouldn’t 06-25 be June 25, not August?

4

Depends if it is a secure connection. Certificate validation requires a correct date and time setting.

So it could be a “chicken-egg” problem. Can’t connect because the time is wrong. Need to connect to set the time.

I have the same problem - where can I find how to set the time through the command line?

Anyone figure this out? I’m having exact same issue.

Well, I’ve spent 2 days fighting this without a resolution. At this point, I’m taking this as a sign to stay with SmartThings. It’s bad when you follow the “Easy” installation to the letter and still can’t get past the installation.

I’ve managed to fix the time issue by creating a USB stick named CONFIG, creating a new file named timesyncd.conf and adding

[Time]
NTP=0.pool.ntp.org 1.pool.ntp.org 2.pool.ntp.org
FallbackNTP=time.google.com time.cloudflare.com

Ensure the USB is inserted into the rpi before first boot, otherwise you’ll need to re-flash the sd card.

At the same time I setup ssh so I could check the correct time and debug if needed (for me it wasn’t).

That fixed the problem. Thanks pinconesalt. I was trying to install HA on a Raspberry Pi5 4GB. I was getting “Failed to start. Wait Until Kernel Time Synchronization” error during the OS installation stage.

Steps taken: -

  1. Create an SD card with the HAOS on it. My HA version was 16.3.
  2. Get a USB stick, name the USB stick volume as CONFIG. Create a file called timesyncd.conf on the USB stick and add the data in the file outlined by pineconesalt’s instructions. Make sure the file is named timesyncd.conf and NOT timesyncd.conf.txt
  3. Plug the USB key into a spare USB port on the Raspberry Pi, place the SD card into the Pi.
  4. Power up the Pi and you should see it unpack and expand HAOS.
    This time I did not see any “Failed to start” errors. And navigating to the homeassistant.local:8123 URL all looks fine.

Hey Guys,

I got stuck with this too while setup. Creating the stick worked for me, too!

Thx a lot!

I’m seeing other people doing a second boot remedies the problem you are bypassing by configuring the Raspberry Pi to start ntp synchronisation earlier in the install process.
The latest release may also remedy the issue. It -waa- reported to the developers in GitHub, wasn’t it?
