Trying to update.

[C4Wiz]

i just installed Home Assistant on a Khadas vim3 using the 15.2 rescue image, works great, when i go to update it says none available.

looking through the logs i found this:

2025-11-13 16:49:34.806 INFO (MainThread) [supervisor.os.manager] Fetch OTA update from https://os-artifacts.home-assistant.io/16.3/haos_vim3-16.3.raucb
2025-11-13 16:49:35.192 ERROR (MainThread) [supervisor.os.manager] Error raised from OTA Webserver: 404

and

2025-11-13 16:53:44.705 WARNING (MainThread) [supervisor.updater] Board 'vim3' not found in version file. No OS updates.

looking at the url on the github page i noticed ithe update file is named: haos_khadas-vim3-16.3.raucb but the updater is looking for haos_vim3-16.3.raucb.

how can i fix this?

i Fixed it.

for anyone facing this issue: https://docs.khadas.com/software/oowow/user-manual
you can push the HAimage over lan:

first change firewall settings:

Firewall
Network → Firewall Mode:

block - Block all incoming connections SECURE (Default)
allow - Allow incoming connections from local networks RECOMMENDED
disabled - Allow all connections, firewall disabled DANGER

then:

curl OOWOW_HOST_NAME_OR_IP/shell/write | sh -s - IMAGE

I used OOWOW today for the first time and I confirm that this behavior is reproducible. There's something sketchy with the image provided by Khadas in their mirror - not only it is not the official image from our releases, but it also has wrong compatible field set in its metadata which results in incompatibility with updates published here. I will investigate if there are more differences, but nevertheless I'll contact Khadas about this discrepancy, as it leaves all users who used this method stranded on an old OS version.

Using another installation method (like the curl method you've used) using an image obtained from HAOS releases page is the way to go indeed.
