## Cloned from bugzilla 1917076 ##

Description of problem: Pulp solves the wrong dependent packages which will cause conflict to other packages.

Steps to Reproduce:

1. Enable the pulp debug log level and restart Pulp services
2. On Satellite Web UI, create a content view name "cv_rhel_8", set the "solve dependencies" to "Yes"
3. Add "Red Hat Enterprise Linux 8 for x86_64 - BaseOS (RPMs)" repository to the CV.
4. Create a filter to include all errata until 1st Oct 2020.
5. Create a filter to include all rpms without errata.
6. Publish the content view
7. Register a rhel 8 host to the CV.
8. Run dnf update on the host.

Actual results: Update with dependencies issue as below:

Expected results:

1. No problem in libsolv while publishing the CV.
2. Either nothing to update (depend on the rhel8 version) or update packages without problem.

Additional info: While checking the above log, you should notice that the "nevr" of the rpm is not correct, such as "iwl3160-firmware-1:25.30.13.0-noarch.noarch". This is causing many same rpm versions are parsing to libsolv. Libsolv complains that it can't install the same version of rpms like below:

"cannot install both iwl3160-firmware-1:25.30.13.0-noarch.noarch and iwl3160-firmware-1:25.30.13.0-noarch.noarch" "cannot install both libtirpc-0:1.1.4-i686.i686 and libtirpc-0:1.1.4-i686.i686"

Below is the offending line in the code. It sets the "r" to "arch", but it should be set to "release".

https://github.com/pulp/pulp_rpm/blob/2-master/plugins/pulp_rpm/plugins/importers/yum/pulp_solv.py#L227

Amending this line seems to solve the issue. Libsolv doesn't complain any problem. The libsolve transaction (transaction.newsolvables() method) pulls the correct number of rpms (which is equal or more than to the associating rpms)
