[Pkg-mongodb-maintainers] Bug#858903: Mongodb server fails to install if there is 'mongodb' user already in system.

[Marcin Juszkiewicz]

Package: mongodb-server
Version: 1:3.2.11-2
Severity: normal

I am using Kolla to build container images with OpenStack components.
One of images contains mongodb. And it fails to build.

Part of build is creation of users with fixed UID/GID values. Which
works fine for most situations as packages usually are fine with user
accounts already existing. But not mongodb ;(
