Remove residual rpm packages after deleting the Requires dependencies

[xiacunshun]

Generally requests for new features should be opened as a Discussion first. There feedback from the community can be collected and possible solutions can be discussed. Consider maintaining a design outline in the top post and update it as the discussion progresses. After a plan of action has solidified an issue for actually implementing it can be created.

Is your feature request related to a problem? Please describe.

When I remove the unnecessary 'Requires:' of one package, I found that the residual package which is no more required can not br removed when upgrade. I tried 'Obsoletes', but I found that it affects other packages that requires it. For example, in package A, if 'Requires B' is removed and 'Obsoletes B' is added, then another package C that 'Requires B' cannot be installed.

Describe the solution you'd like

Something like 'Obsoletes' that can only remove unneccesary requires of current package.

Impossible to give any detailed response because there's almost no info provided on what was done and so on, but: if a package cannot be removed after removing another one, then it sounds to me like that package is missing a dependency on the removed one. Also, if you used 'rpm --nodeps' (the most common way of ending up with broken dependencies) then you get to keep all the pieces.

It's also not a feature request of any kind. Questions like this is what the Q&A department in the discussions is for.

I apologize if my previous description was not very precise. What I meant to say was that if A originally depends on B, and we remove the "Requires B" from the spec, the next time we upgrade A using "dnf upgrade" or "rpm -U", it will not simultaneously remove B. This is different from the effect of directly using "dnf remove A", because the latter will remove unused dependencies B.
