I've tagged in (and gotten signed) lorax-35.0-3.eln110
Let's try a compose and see if that fixes things.

Nope, still failing with the same error.
I double checked that it was installing lorax and lorax-templates-generic 35.0-3.eln110.

@hanzz
I've been trying to dig in and figure out what happened here, but I'm not having any luck. Can you help?

@hanzz identified and fixed this issue today with a hack, but we need a more robust long-term solution (tracked as #46)
