Detailed Description

DNF-2.0 is the next upcoming major version of DNF package manager. Unfortunately, it brings some incompatibilities with previous version of DNF (DNF-1) which were either needed to preserve compatibility with YUM CLI or where bigger redesigns were needed. A list of identified incompatible changes can be found here[1].

Benefit to Fedora

New major version of DNF brings many new features and bug fixes. Moreover, the support period of older versions is reaching its end.

Scope

• Proposal owners:
  • complete release notes 
  • deliver DNF-2.0 stack to Rawhide
• Other developers:
  • Owners of 3rd party DNF plugins or components depending on DNF should check and adjust their packages otherwise they may not work with DNF-2.0.
• Release engineering:
  • All release engineering tools that depends on DNF should be tested against DNF-2.0.

Upgrade/compatibility impact

Enduser compatibility should be preserved as much as possible. We do not expect any manual user intervention.

How To Test

• early adopters are welcomed to use this COPR repo for testing
• testing scenarios:
  • anaconda installation
  •  upgrade from previous Fedora version
  • core functionality: install, upgrade, remove, repoquery
  •  dnf-plugins: copr, system-upgrade, download
  • third party software: mock, yumex

User Experience

Contingency Plan

  • consequent rollback of already ported components
• Contingency deadline: F26 Alpha Freeze
• Blocks release? Yes
