Installation

Hi folks,
I have been trying to update HAOS for ages to no avail.
Keeps failing at Can’t fetch OTA update from https://os-artifacts.home-assistant.io/17.2/haos_ova-17.2.raucb.
VM is running on VirtualBox 7.2.
Plenty of disk space. Plenty of VRAM.
Help appreciated.

You can try to do this manually.
Get a proper shell then run

cd /mnt/data
curl -vLO https://os-artifacts.home-assistant.io/17.2/haos_ova-17.2.raucb
rauc install -d haos*.raucb
ha host reboot

There’s also a way via USB:

Just drop the file in the root directory as per docs.
Similar instructions to above are here: https://developers.home-assistant.io/docs/operating-system/update-system#using-update-bundles
Not that this should be needed though. What’s the supervisor logs say?

Thanks Impact you Legend,
Shell command worked a treat.

Just curious, what was the actual problem that was fixed here\the root cause of the problem?

I don’t know what the problem was, I didn’t see the supervisor logs.

Hi guys! My issue is similar. Could anyone tell me why I cannot update it from OS 16.3? This issue is on since the first stable release of OS 17.0 (19th Jan)
The installation run “successfully” without error or without any message but nothing happen at the end. I am relative new here as I started HA with the OS 16.3 in december 2025. Core updates run fine. Tried also dig the logs but found nothing special (at least for me).
Thank you! (Generic x86-64 laptop)

Open your laptop & you should see the HA console on screen.

Type in ha os update --version 17.2 (or simply ha os update, since 17.2 should be the latest version). The console will tell you what’s going on during the update.

Thank you! Just solved it yesterday night. It was the “Slot B” issue. It runs on 17.2 now. :slight_smile: (I really do not know that it is good or not as did not noticed any pro/contra differences yet)
