Hello all

Tonight I installed Fedora 27 and after I ran a dnf upgrade to update all of my packages, I tried to run the dnf group list command after reboot and I was given the following errors:

# dnf group list

yum group list gives me the same error as well.. Any ideas on what I should do to fix this? It is strange that this distro's package manager would break after a single system upgrade. All help is greatly appreciated! thanks
