Replace Comps Language Group With Langpacks


Language support groups in Comps file will get replaced by weak rich dependencies in the langpacks package.

With this Change meta-packages like langpacks-ja will also install required fonts and input-methods for the given language.

Detailed Description

This change will remove the need of having the language specific comps groups in Fedora

langpacks-* meta-packages have been in Fedora since F24. Currently they only install locales, translation langpacks, and dictionaries, but not fonts or input-methods, etc. With this Change they will install required fonts and input-methods for a language as well.

e.g. When you do a net-install of Fedora in Japanese then with langpacks-ja the installation of any base package like libreoffice-core or man-pages causes libreoffice-langpack-ja or man-pages-ja to be installed. After this change using weak dependencies like Supplements in langpacks, Japanese fonts and input-method can also get installed if appropriate.

Then there is no need for language comps groups to exist: they will be handled by the langpacks package.

See for more background discussion.

Benefit to Fedora

Users can install complete language support now using langpacks only. This will also help to remove the language support groups from the comps file.


  • Proposal owners: Check all langpacks providing packages (like fonts, input-methods) add Supplements tag in their SPEC file and build them. We will track the progress of this Change in Langpacks Copr project.
  • Other developers: To all other developers of packages who provides langpacks, they need to add the Supplements tag as given in this Langpacks guideline to each langpack subpackage.
  • Release engineering: none
  • Policies and guidelines: none

Upgrade/compatibility impact


How To Test

User Experience

Currently users can get complete language support installed only using "dnf group install <lang-support>" command. After this Change gets implemented end users can get language support installed using meta-packages "langpacks-<langcode>" only


No Other Change depend on this.

Contingency Plan

  • Contingency mechanism: If this change is not completed by final development freeze then we need to target this for F31. We are just proposing to add additional information in langpacks packages that is Supplements tag. This should not affect individual langpacks packages installation by dnf.
  • Contingency deadline: I don't think we will need anything to revert or apply any contingency plan here if this is not completed by beta freeze.
  • Blocks release? No
  • Blocks product? N/A


  • Need to add about this in the Release notes
