What exactly are "Related Packages”?
Related packages are sub package of main package or point to main package.
For example I choose opencv and spec file Tree - rpms/opencv - src.fedoraproject.org
As you can see in spec file there are some other packages like “python3-opencv” or “opencv-contrib” which they are subpackage and If you like any of them in packages.fpo it will also point to main package. it is basically show which package come where or where to belongs to.
Bumping your own post is not an encouraged practice.
I noted you did that with 2 different posts about 8 hours ago.
Please wait and allow others time to read and respond since the forum spans the globe and only waiting for about 7 hours to bump it seems just a bit rude and expects immediate response.
We are not a paid support center where one expects an immediate response 24x7.
