Description of problem:
I was installing some rpms using a wildcard, and saw the message
"Package … not installed, cannot update it.", even though the package
was clearly present. It is because dnf warns about the source package
without giving any hint that it is a source package.

Version-Release number of selected component (if applicable):
dnf-1.1.9-2.fc24.noarch

Actual results:
$ sudo dnf upgrade /var/lib/mock/fedora-24-x86_64/result/systemd-229-11.fc24.src.rpm
Package systemd not installed, cannot update it.

Expected results:
$ sudo dnf upgrade /var/lib/mock/fedora-24-x86_64/result/systemd-229-11.fc24.src.rpm
Package /var/lib/mock/fedora-24-x86_64/result/systemd-229-11.fc24.src.rpm is a source package and cannot be updated, ignoring.
