Red Hat is committed to replacing problematic language in our code, documentation, and web properties. We are beginning with these four terms: master, slave, blacklist, and whitelist. Because of the enormity of this endeavor, these changes will be implemented gradually over several upcoming releases. For more details, see our CTO Chris Wright’s message.

Chapter 2. Known issues
Copy link

  1. The dnf command is not available.

    To reduce image size, .NET 7.0 container images use the ubi-minimal base image instead of the ubi base image. The ubi-minimal image uses the microdnf command as its package manager instead of the dnf command.

    If your Dockerfiles/Containerfiles use the dnf command, you must change them to use the microdnf command instead.

    For more information about the microdnf command, see the microdnf man page.

See Known Issues in the .NET 7.0 Release Notes for .NET 7.0 RPM packages for a list of known issues and workarounds for RPMs.
