I have this error with a device that’s out in the wild. I’m not able to restart or reboot the device. I am able to ssh into the host OS though
I took a look at your device and it appears the balena daemon binary has become corrupted. It’s not clear why this occured, but what I did manage to do is replace the binary with a known working one from the same OS version. Things seems to be working fairly well now, but the initial cause of corruption could strike again.
Let me know if you encounter any other issues!
