Hello, We have an older AFS server, which was running Centos 5.5. It hasn't been updated in a while because of the plans to move it to another server, but it never happened. Thus, we've decided to upgrade it to 5.7… I did yum clean all and yum update. Everything ran smoothly and no issues. After the reboot, zlib.so.1 can no longer be found. /usr/lib64/zlib.so.1 is a symbolic link to /lib64/zlib.so.1, but the file does not exist. Because of this, ssh/yum/rpm do not work… I've been googling, but can't find a solid answer. This is a production server and I need to have it up and running as soon as possible… Any ideas? Thank you! Asya
