Description Laszlo Ersek 2016-10-19 20:35:41 UTC 
*** Description of problem:
When the user only knows the name of a subpackage, but not that of the main (source) package, and the subpackage is not installed on the system (so that "rpm -q --info" cannot be used), then "yum info SUBPACKAGE" used to provide this information (that is, leading the user from the subpackage to the main package). Dnf does not print this information.

*** Version-Release number of selected component (if applicable):
dnf-1.1.10-1.fc24.noarch

*** How reproducible:
100%

*** Example Steps to Reproduce:
1. On a Fedora 24 system,
   run "dnf info gcc-aarch64-linux-gnu"
2. On a RHEL-7 system with EPEL-7 enabled,
   run "yum info gcc-aarch64-linux-gnu"

*** Actual results:
The output of command #1 does not contain the "Source RPM" field.
The output of command #2 contains the "Source RPM" field
(namely cross-gcc-XXX.src.rpm).

*** Expected results:
"dnf info" should print the Source RPM field as well, because for some packages, the main package name cannot be deduced from the subpackage name.

*** Additional info:
If the subpackage is already installed on the system, or downloaded to a local file, then the command "rpm -q --info [-p SUBPACKAGE.rpm]" can be used to retrieve the same kind of information. However, the name of the SRPM should be retrievable without such restrictions.
Comment 1 Jaroslav Mracek 2016-10-21 16:11:28 UTC 
I think that the problem was solved in DNF-2.0, that was released into rawhide. The testing version is available for fc24 in copr repo rpmsoftwaremanagement/dnf-nightly. Here I provide reduced output with and without verbose mode for dnf-2.0.0_0.rc1.1-11g5945ec5.fc24.noarch. Please can you confirm that you are satisfied with changes?

Comment 2 Laszlo Ersek 2016-10-21 17:20:52 UTC 
Looks perfect. Printing the Packager in the verbose view is a nice touch also; that's something that yum prints as well, IIRC.

So I guess this BZ can be set to CLOSED/NEXTRELEASE, can it not?

Thank you very much!
