Hi, Starting from about a week ago my yum update fails. I have the same issue as described in: http://lists.caosity.org/pipermail/centos-devel/2004-December/000488.html It seems that when there is a repo without signatures and it tries to install a package from there it fails. I get: <snip> Total download size: 254 M Is this ok [y/N]: y Downloading Packages: (1/96): python-twisted-1. 97% |======================== | 2.6 MB 00:01 ETA warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID 30c9ecf8 (1/96): python-twisted-1. 100% |=========================| 2.7 MB 01:45 Could not open local rpm file: //var/cache/yum/development/packages/python-twisted-1.3.0-3.i386.rpm then it aborts I tried a yum clean all but that didn't help Sander
