Description of problem: I'm running Fedora 20 with the rhughes copr repo for GNOME 3.12. Upon trying to update my system with dnf, I get the above error. It seems to be related to updates from GNOME 3.12. This happens everytime I try to update with dnf. When I use yum I get dependency issues. Version-Release number of selected component: dnf-0.4.20-1.fc20 Additional info: reporter: libreport-2.2.1 cmdline: /usr/bin/python /usr/bin/dnf update -y executable: /usr/bin/dnf kernel: 3.13.9-200.fc20.x86_64 runlevel: N 5 type: Python uid: 0 Truncated backtrace: package.py:52:chksum:AttributeError: No such checksum.
