i've tried to upgrade to fed 28, but got the same error after
downloading and pressing yes to GPG-key
Curl error (37): Couldn't read a file:// file for
file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmfusion-free-fedora-28 [Couldn't
open file /etc/pki/rpm-gpg/RPM-GPG-KEY-rpmfusion-free-fedora-28]
should i try just a fresh installation of fed 28 or is there any other way?
