I did something stupid. I simply `scp`ed my *rpmforge* repo files from another (working) machine on to my dev box, and ran `yum update`. This yielded:

```

Oops. I didn't [follow the directions](http://wiki.centos.org/AdditionalResources/Repositories/RPMForge). So I deleted the `*rpmforge*` files from `/etc/yum.repos.d/`, and started over the correct way. Which all went fine until I tried another `yum update`:

```

I suppose I could just delete those files, but I want to be sure that by getting a bigger hammer, I'm not just breaking my system in to smaller pieces first.

How should I fix this?
