RPM Support

Hi Guys

I am unable to sync the Extra Packages for Enterprise Linux (EPEL) 7 remote with a repository. The tasks ends with the error below. I tested different policies (immediate, on_demand) and with or without validation. The result is always the same. Other RPM remotes are syncing fine. Pulp 3 was installed using the ansible installation method.

If you need me to do any further testing please let me know.

Thanks

Steps to reproduce:

http POST http://localhost:24817/pulp/api/v3/remotes/rpm/rpm/ name='epel7-x86_64' url='https://dl.fedoraproject.org/pub/epel/7/x86_64/' policy='on_demand'
http POST http://localhost:24817/pulp/api/v3/repositories/ name='epel7-x86_64'
export REMOTE_HREF=$(http :24817/pulp/api/v3/remotes/rpm/rpm/ | jq -r '.results[] | select(.name == "epel7-x86_64") | ._href')
export REPO_HREF=$(http :24817/pulp/api/v3/repositories/ | jq -r '.results[] | select(.name == "epel7-x86_64") | ._href')
http POST :24817${REMOTE_HREF}sync/ repository=$REPO_HREF

Result:
