The image corruption message is related to a container, telling you there’s an issue with image layers stored on the device. Have you tried restarting the device (or restarting resin-supervisor)? It sounds like the image from a previous push failed.
BTW, actions such as Restart and Purge data from the balenaCloud dashboard will not apply to local mode containers. When switching out of local mode and back to tracking releases from balenaCloud, the Supervisor will destroy any local mode containers and volumes, as well as clean up unneeded base images, and then start up the application that balenaCloud instructs it to run. If you have no cloud-based images (because you didn’t push to the application, just the local host), there would be no cloud image to restore, just a local one.
