Just create a C1 instance with Ubuntu 18.04 and try running “apt update && apt upgrade”. It will throw an initramfs error which cannot be fixed by the user.
Same issue here.
Upgrade throws the error, hangs on for a while then exits silently.
Containers keep running on my servers, but this doesn’t sound good at all.
Saw this also with the original 16.04 image on my C1 instance.
The initramfs update is looking for the disk by uuid, which is simply not there.
