Hi all,

i have a problem with centos's up2date tool. I have setup a central update server with yam (http://dag.wieers.com/home-made/yam/) under CentOS-4. When yam calls t up2date to download updates, up2date returns this error:

Traceback (most recent call last): File "/usr/bin/yam", line 1099, in ? main() File "/usr/bin/yam", line 983, in main mirror(dist.repos[repo], srcdir, dist) File "/usr/bin/yam", line 632, in mirror mirrorrhn(url, path, dist) File "/usr/bin/yam", line 870, in mirrorrhn package_list, type = rpcServer.doCall(repos.listPackages, channel, None, None) File "/usr/share/rhn/up2date_client/rpcServer.py", line 316, in doCall ret = apply(method, args, kwargs) File "/usr/share/rhn/up2date_client/repoDirector.py", line 21, in listPackages return self.handlers[channel['type']].listPackages(channel, msgCallback, progressCallback) KeyError: 'up2date'

How can I fix this?? Can up2date from centos download packages from rhn.redhat.com website?

Thanks.
