On my 18.04 laptop it is group shadow and group readable. If anyone can still reproduce this, please re-open this bug. It is likely an intaller bug.

On the latest ubuntu 16.04 LTS the ownership of /etc/shadow is still not fixed. To my understanding it should be -r--r----- 1 root shadow to conform to legacy programs as well and not -rw------- 1 root root as it is on a new install.
