System update fails. When config was previously working. With “Could not open path to sync”
We created our own pi image using mender-convert to increase the root disk size. Then created a system artifact using mender-artifact. And successfully deployed it to a new device with the raw pi image from the mender-convert step. This was on 15-Aug-2025, I believe that the mender-update version was 5.0.1.
But now it is not working. I am trying to deploy the same system artifact to a new device with the raw pi image mender-update version 5.0.3 (installed using the copy paste commands given in the ‘connect new device’ tab on the devices dashboard) I get this log output. looks like the path is uninitialized.
