Hi, I've been trying to use yum for the first time. It's working fine on the whole, but if I try to yum update everything it complains about some modules not being signed and bombs out. One such is kernel-devel and I can easily and quickly provoke that one by typing: yum update kernel-devel After the download (which is now in the cache so doesn't get re-downloaded) I get the following and it stops: unsigned package kernel-devel-2.6.11-1.1341_FC4.i686.rpm Is there some way to have it allow unsigned packages to be installed, or to keep going and install the other modules after this error.
