Description of problem:

Add the following repo. to yum.repos.d, dnf refuses to download the metadata:

[fm-group:core]
name = Fedora $releasever auto modularity, @core
baseurl = https://fedorapeople.org/groups/modularity/fedora-$releasever-mod/@core
enabled=1
metadata_expire=28d
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$releasever-$basearch
skip_if_unavailable=False

...from what I can see it's a problem in librepo, and it's probably due to the repo. using the --baseurl feature of createrepo. dnf fails in the same way if you copy it locally and use a file: as the baseurl.


Version-Release number of selected component (if applicable):
% rpm -q dnf
dnf-1.1.9-1.fc23.noarch

How reproducible:
Always
