Upgrading 4.0 -> 4.1-RC1: No Match for argument qubes-dist-upgrade

I’m trying to do the in-place upgrade. But, when I run

sudo qubes-dom0-update -y qubes-dist-upgrade

I get the following message:
“No Match for argument qubes-dist-upgrade”

Anyone else getting this?

Never mind. I realized I forgot to enable the testing repos. It worked, once I enabled the testing repos.
