yes,I use fc6. I got the key from rpm --import http://archives.fedoraproject.org/pub/archive/fedora/linux/core/6/i386/os/ and then I did: yum in stall fedora-ds ,but there is the same problem!! 1- in above link there are RPM-GPG-KEY-fedora <http://archives.fedoraproject.org/pub/archive/fedora/linux/core/6/i386/os/RPM-GPG-KEY-fedora> and some other keys which one should I use? only RPM-GPG-KEY-fedora<http://archives.fedoraproject.org/pub/archive/fedora/linux/core/6/i386/os/RPM-GPG-KEY-fedora> ? 2- in http://directory.fedoraproject.org/wiki/Download ,in addition of the key problem, there are some problems for centos5 . should I do those too? for example: yum install svrcore mozldap perl-Mozilla-LDAP libicu <http://archives.fedoraproject.org/pub/archive/fedora/linux/core/6/i386/os/RPM-GPG-KEY-fedora> -------------- next part -------------- An HTML attachment was scrubbed...
