dnf config-manager is a command-line tool for modifying DNF (Dandified YUM) repository settings on Fedora, RHEL, CentOS Stream, and other RPM-based systems. It simplifies enabling, disabling, adding, or inspecting repositories defined in /etc/yum.repos.d/ without direct file editing.

Key features include pattern-based matching for repository IDs (repoids), dumping config variables for verification, and explicit control over enabled/disabled flags. For example, enable a repo with --enable repoid, disable with --disable, or set flags precisely using --set-enabled=1. Adding repos from remote .repo files is supported via --add-repo.

Changes are previewable with --dump and persisted using --save or implicitly. It supports glob patterns like *debug* for bulk operations. Integrated with DNF's caching and security, it's vital for curating trusted package sources, troubleshooting updates, or automating repo management in scripts.

Typically run as root, it ensures safe handling of system-wide configs, reducing errors from manual edits.

Requires root privileges (use sudo). Modifies /etc/yum.repos.d/ files; backup first. Some actions need --save to persist. Glob patterns may match unexpectedly; test with --dump. Not for runtime repo changes—run dnf clean all after.

sudo dnf config-manager --enable crb
sudo dnf config-manager --set-enabled=0 fedora-debug
sudo dnf config-manager --add-repo https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
sudo dnf config-manager --dump '*'

List available repos: dnf repolist all. IDs are lowercase, like fedora, updates.

Introduced with DNF 1.0 in Fedora 22 (2015) as successor to yum-config-manager. Enhanced in DNF 4+ with better glob support and integration. Actively maintained for RHEL 8/9 and Fedora.
