  • Targeted release: Fedora 24
  • Last updated: 22-Jan-2016
  • Tracker bug: []

Detailed Description

This is similar to what we have dnf langpacks plugin which is already in Fedora but there is one missing thing that this plugin currently does not provide automatic installation of langpacks. E.g. if you enable or install Fedora in Japanese language then installation of any base package like libreoffice-core or man-pages are not installing automatically libreoffice-langpack-ja or man-pages-ja. This is because dnf is not providing required hook to re-resolve the transaction unlike yum. But now with using RPM tags or weak dependencies like Supplements, we just need to ensure we have langpacks-xx metapackage is already installed on the system and when a base package is getting installed, it will pull its langpack for that xx language automatically in the transaction set.

This will help in anaconda installation also. When particular set of languages are selected in anaconda then anaconda should pull all the required langpacks in the same initial installation.

Benefit to Fedora

Users will get langpacks for the given language installed. This Change provides language metapackages which user need to just install and they will get all available langpacks for which base package is already installed on the system.

Scope

  • Proposal owners: Check all langpacks providing packages add Supplements tag in their each langpack subpackage. Create metapackages like langpacks-<langcode>.
  • Other developers: To all other developers of packages who provides langpacks, they need to add the Supplements tag as given in this draft guideline to each langpack subpackage.
  • Release engineering: N/A

Upgrade/compatibility impact

None.

How To Test

User Experience

Users will get langpacks installed when they do initial installation of Fedora using anaconda. Users can enable languages by installing metapackage langpacks-<langcode>. Users can find which languages are providing langpacks by executing "dnf search langpacks- " command.

Dependencies

No Other Change depend on this.
