uh... dnf group list is broken in Fedora 27 after system update

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:

Code:

# dnf group list

    ret = comps.fromxml_f(fn)

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

Looks broken here too. Check if a bug has been raised, and if not open one yourself.

My Rawhide system claims it's up to date (although looking at Koji suggests otherwise)

Code:

python3-3.6.4-3.fc28.x86_64
dnf-2.7.5-5.fc28.noarch

dnf group list works as expected

Had the problem hours ago, and just did the following minutes ago and got it resolved.

What I did:
`sudo dnf clean metadata`
`sudo dnf update`
