flash-kernel failure during apt-get upgrade. Now what?
I just did an apt-get upgrade to apply the DSA-3791-1 security update from
two days ago, and flash-kernel produced this warning for both the kernel and
initramfs:
File does not seem to match flash data.
I'm now afraid to reboot this box (a QNAP TS-119P+ NAS) in case corrupt
kernel and initrd images have been written to flash. The system has been
running debian for several years now, and through dozens of kernel updates,
I've never seen this before. Can someone advise on how to proceed?
Here's the full output:
