Override/Merge Repository Configurations Instead of Throwing Error: "Repository is listed more than once in the configuration"

[RomanSoloweow]

Hi,

We are using the latest version of DNF v4.

I have a scenario where myConfig.repo contains a repository configuration, and I want to override some parameters using a separate file, myConfig-override.repo, which has the same repository ID but includes modified parameters. However, when I try this, I encounter the error: "Repository is listed more than once in the configuration".
Is there an option or plugin available in DNF v4 that allows for overriding or merging repository configurations as described?

I noticed that this feature is available in DNF v5, but I cannot use it since not all operating systems I work with support DNF v5 yet.

Thank you for your help!

Hi, I don't think DNF 4 has or will implement something like DNF 5's drop-in repo directories, sorry. From quickly looking around, I don't see a plugin that implements this either, although it may be possible.

However, if you are in a position where you are able to make changes to myConfig.repo, you could allow users to override settings using DNF 4's relatively new variable expansion feature. See https://dnf.readthedocs.io/en/latest/conf_ref.html#repo-variables. For example, you could have:

# /etc/yum.repos.d/myConfig.repo
[myConfig]
name=Example myConfig repo
metalink=https://example.com
enabled=${ENABLE_MY_CONFIG:-1}

enabled will be 1 by default unless ENABLE_MY_CONFIG is set. So if a user wanted to override the default, they could echo 0 > /etc/dnf/vars/ENABLE_MY_CONFIG. Could that help your use case?
