Description Laurie Reeves 2020-02-06 22:02:09 UTC

Description of problem:
When doing a dnf list or download command, the repository priority is not used. However, the actual install will install the package from the correct repository.

Version-Release number of selected component (if applicable):
Current versions from Fedora 31:
dnf.noarch                              4.2.18-1.fc31
dnf-plugins-core.noarch                 4.0.13-1.fc31
libdnf.x86_64                           0.43.1-1.fc31 
libmodulemd.x86_64                      2.8.3-1.fc31 
librepo.x86_64                          1.11.1-1.fc31 
libsolv.x86_64                          0.7.11-1.fc31

I also played around with experimental builds from koji, but got the same results.

How reproducible:
100%

Steps to Reproduce:
In general terms, find a package with a higher version in a repository with a lower priority (higher priority value). 'dnf list' and 'dnf download' will both provide the higher version from lower priority repository. However, 'dnf install' will correctly provide the lower versioned package from the higher priority repository.

An example:
1. Currently, Fedora 31 'updates' repository has youtube-dl version 2020.01.24, updates-testing has version 2019.09.12.1.
2. Remove youtube-dl from system if installed.
3. Edit fedora-updates-testing.repo to make 'updates-testing' priority=1 (making the repository with the lower version higher priority).
4. dnf --disablerepo=* --enablerepo=updates,updates-testing list youtube-dl
5. dnf --disablerepo=* --enablerepo=updates,updates-testing download --url youtube-dl
6. dnf --disablerepo=* --enablerepo=updates,updates-testing install youtube-dl

Actual results:
The list and download commands both provide version 2020.01.24. The install command provides version 2019.09.12.1.

Expected results:
All three commands should provide the 2019.09.12.1 version.

Additional info:

My actual use-case involves dnf download with --resolve --alldeps in an empty root to populate an install tree. This functionality is vital.

Priorities worked correctly with 'yumdownloader' on Centos 6.
