I am unable to install mongodb community and enterprise in the 6.0 repos as of this morning. I think it's possible that a package we depend on stopped also depending on shadow-utils. Here is a docker image definition that reproduces the error:

FROM amazonlinux:2023
RUN echo $'\n\
[mongodb]\n\
name=MongoDB Repository\n\
baseurl=https://repo.mongodb.org/yum/amazon/2023/mongodb-org/6.0/x86_64/\n\
gpgcheck=1\n\
enabled=1\n\
gpgkey=https://pgp.mongodb.com/server-6.0.asc' > /etc/yum.repos.d/mongodb.repo
RUN yum install -y mongodb-org

Error logs:

This has come up before – I wonder if we should do an audit to ensure we're installing shadow-utils on every server version?
