Hi,

I’m using Mender rootfs-image OTA updates on a Rasp Pi 4.
The provisioning image/mender artifact is built from an official Rasp Pi OS 64-bit Lite (Debian trixie) golden image using mendersoftware/mender-convert:5.1.0.

Application update is working but during an OS update:The artifact downloads successfull then partition is written , the devices starts reboots, after reboot, the deployment always fails with:

The device always boots back into the original rootfs, and the update is marked as failed. No explicit kernel or filesystem errors appear in system logs.What conditions must be satisfied for ArtifactVerifyReboot to succeed on Raspberry Pi rootfs-image updates?

Thanks

Hi @sushil,

There is a 3 minute gap in your log:

2026-01-27 09:43:08.096 +0000 UTC info: Termination signal received, shutting down gracefully
2026-01-27 09:46:07.787 +0000 UTC info: Running Mender client 5.0.3

A simple reboot should not take 3 minutes, so my guess is that there is something happening in between there. The most obvious thing would be two reboots, and the device not connecting to the server in between. So I’d suggest to watch a device which exhibits this behavior, and try to see what’s going on.

Greetz,
