Current status

• Targeted release: Fedora 30
• Last updated: 2019-01-28
• Tracker bug: <will be assigned by the Wrangler>

Detailed Description

Remove packages from the distribution:

• createrepo
• yum
• yum-langpacks
• yum-utils
• yum-metadata-parser
• yum-updatesd
• python-urlgrabber

All these packages should no longer be used and all software using them should be migrated to DNF.

Compatibility:

• Important packages such as yum, createrepo or yum-utils will be provided/obsoleted by relevant packages from the dnf stack
• Important executables such yum, repoquery, createrepo, etc. will be provided either as new executables or via symlinks

Benefit to Fedora

Drop an old package manager that has no active upstream development. Move existing users to DNF which that has active development. Secondary benefit is reducing number of packages in Fedora that still depend on Python 2.

Scope

• Proposal owners: Remove packages from the distribution: createrepo, yum, yum-langpacks, yum-utils, yum-metadata-parser, python-urlgrabber
• Other developers: Either remove packages from the distribution or switch them to DNF
• Release engineering: #7588
  • List of deliverables: N/A (not a System Wide Change)

• Policies and guidelines: N/A
• Trademark approval: N/A (not needed for this Change)

Upgrade/compatibility impact

Any tool based on YUM 3 Python API will stop working. This applies on any 3rd party software which won't be changed in Fedora as part of this change. CLI compatibility will be provided by DNF.

How To Test

Repoclosure passes after dropping the packages.

User Experience

There shouldn't be any impact on YUM users because the functionality is provided by DNF already. Users of tools listed in the Dependencies section shouldn't see any difference if the migration to DNF is done properly.
