Hi, In the version of 5.4 currently on rsync.scientificlinux.org, the following packages are unsigned: i386: iproute-2.6.18-11.el5.i386.rpm rgmanager-2.0.52-1.el5_4.2.i386.rpm x86_64: iproute-2.6.18-11.el5.x86_64.rpm jdk-1.6.0_16-fcs.x86_64.rpm (known issue I think) rgmanager-2.0.52-1.el5_4.2.x86_64.rpm Also on x86_64, the following produce "warning: xxx.rpm: Header V3 DSA signature: NOKEY, key ID e8562897" emacs-21.4-20.el5.x86_64.rpm emacs-common-21.4-20.el5.x86_64.rpm emacs-el-21.4-20.el5.x86_64.rpm emacs-leim-21.4-20.el5.x86_64.rpm emacs-nox-21.4-20.el5.x86_64.rpm They seem to be CentOS rpms? Maybe I just need to import /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5, but I haven't needed to before now. Thanks.
