I'm getting ready to upgrade to Centos-3.1, but I have a database application that is having difficulty. It needs the libstdc++ libraries. When I run it, it generates the following message: error while loading shared libraries: libstdc++-libc6.1-1.so.2: cannot open shared object file: No such file or directory Well, this error doesn't look so bad, as long as I can run Yum on it and get the libraries. Unfortunately, the Yum install fails with a bad GPG key. I've done this Yum install on Centos-2 (for the same library), so I'm not sure why I'm seeing a failure. Here's what I see when I run Yum (I added the -t hoping to ignore the error): [root at linux root]# yum -t install compat-libstdc++ Gathering header information file(s) from server(s) Server: CentOS-3.1 - Addons Server: CentOS-3.1 - Base Server: CentOS-3.1 - Extras Server: CentOS-3.1 - Updates Finding updated packages Downloading needed headers Resolving dependencies Dependencies resolved I will do the following: [install: compat-libstdc++ 7.3-2.96.128.i386] Is this ok [y/N]: y Getting compat-libstdc++-7.3-2.96.128.i386.rpm compat-libstdc++-7.3-2.96 100% |=========================| 1.0 MB 00:23 warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID 025e513b Error: Could not find the GPG Key necessary to validate pkg /var/cache/yum/update/packages/compat-libstdc++-7.3-2.96.128.i386.rpm Error: You may want to run yum clean or remove the file: /var/cache/yum/update/packages/compat-libstdc++-7.3-2.96.128.i386.rpm Error: You may also check that you have the correct GPG keys installed If you have any ideas how to get the libraries, that would be a big help to finishing this move.
