Hi. When I try to use --installroot, I get the following: --- [root at machine ~]# yum --installroot=/data/xchg-2.0/ install apache2 You have enabled checking of packages via GPG keys. This is a good thing. However, you do not have any GPG public keys installed. You need to download the keys for packages you wish to install and install them. You can do that by running the command: rpm --import public.gpg.key Alternatively you can specify the url to the key you would like to use for a repository in the 'gpgkey' option in a repository section and yum will install it for you. For more information contact your distribution or package provider. --- Where is the GPG key I need to import? I've tried: [root at machine ~]# rpm --import /usr/share/rhn/RPM-GPG-KEY-fedora [root at machine ~]# rpm --import /usr/share/rhn/RPM-GPG-KEY [root at machine ~]# rpm --import /usr/share/doc/centos-release-4/RPM-GPG-KEY [root at machine ~]# rpm --import /usr/share/doc/centos-release-4/RPM-GPG-KEY-centos4 But no such luck... Anyone know where to look? Thanks, Morten
