Fedora YUM¶

YUM, the package manager DNF superseded.

On current Fedora and RHEL the yum binary is a wrapper around dnf. mpm drives it exactly as DNF, only the binary name differs.

Version requirement: >=4.0.0

Platforms¶

Operations¶

Operation	Supported	Notes
`installed`	✓
`outdated`	✓
`search`	✓	exact and extended search backfilled by `mpm`
`install`	✓
`upgrade`	✓
`upgrade_all`	✓
`remove`	✓
`sync`	✓
`cleanup`	✓

Ecosystem¶

Accepted purl types: pkg:rpm, pkg:yum

Usage¶

$ mpm --yum installed
$ mpm --yum search "query"
$ mpm --yum upgrade --all
$ mpm install pkg:yum/hello
$ mpm --dry-run --yum upgrade --all

Every example above accepts --dry-run, which simulates the underlying manager calls without touching the system: the safe way to watch what mpm would do before trusting it.

Deselect the manager for a single run with --no-yum, disable it from your configuration, or tune its invocation attributes with per-manager overrides.

Command line¶

CLI names, in lookup order: yum
Arguments forced before each call: --color=never --quiet

The version is extracted from the output of yum --version with:

r"(?P<version>\S+)"

Privilege escalation¶

System-wide manager: mpm wraps its privileged operations in sudo out of the box. Instead of letting the tool prompt mid-run, mpm primes the credential cache up-front, with a single branded password prompt at most. Turn escalation off for rootless setups with --no-sudo or the per-manager sudo override.

See privilege escalation for the full policy.

Cooldown¶

State of Fedora YUM’s release-age gating, from the cooldown support table:

Status: ➖ N/A (deprecated alias for dnf on RHEL-family)

With --cooldown set, mpm skips this manager’s install and upgrade operations rather than run them unguarded (fail-closed); --allow-unsupported-managers opts back in.
