Starting from the respeaker-debian-lqxt-sd-20180319-4gb image, doing
sudo apt update
sudo apt upgrade
results in the following error:
Processing triggers for initramfs-tools (0.130) …
ln: failed to create hard link ‘/boot/initrd.img-4.4.95-respeaker-r7.dpkg-bak’ => ‘/boot/initrd.img-4.4.95-respeaker-r7’: Operation not permitted
After this update, the system will not reboot correctly, in the sense that no serial device is presented on the OTG port and any previously-configured networks (either wifi or wired) are unavailable. I do not have a UART-to-USB adapter to test with so I cannot tell if the UART connection would work. Observation of the status lights, though, leads me to believe the system is stuck in a continuous reboot cycle.
The only recovery I’ve been able to find is to reburn the original image.
Do you have any suggestions?
