Public bug reported: Nothing very interesting here, the /boot partition on this server is very small (240M) and the upgrade ran out of space while generating an initramfs image.
I was able to recover by removing the oldest linux-image package. I was surprised that do-release-upgrade didn't check whether there will be enough free space in /boot beforehand.
