Hi,
In the repository selection view menu of Yumex, the rawhide repository is selected, as is expected, but the GPG key icon is missing, so this could be a indication that none of the packages that are downloaded from this repository are actually verified, or its just some error with Yumex, in that it is simply not displayed correctly. I don't know if the same problem applies to Yum. All the other repositories display the icon key.
Bram.
