In commit related to SERVER-55724 mongodb-enterprise-unstable-server package has this:

Provides: mongo-10gen-enterprise-server

which should have been Provides: mongo-10gen-enterprise-unstable-server instead.

To reproduce issue:

• install mongodb-enterprise-unstable-server package
• install mongodb-enterprise-unstable-shell package
• observe:

$ sudo rpm -ivh repo/yum/redhat/8/mongodb-enterprise/5.1/x86_64/RPMS/mongodb-enterprise-unstable-shell-5.1.0-1.el8.x86_64.rpm
error: Failed dependencies:
	mongo-10gen-enterprise-server conflicts with mongodb-enterprise-unstable-shell-5.1.0-1.el8.x86_64
