升级后使用yum报错：

检查次报错原因是依赖无法识别，若版本不需要回退可以添加环境变量解决，
添加环境变量： source /etc/profile
export LD_LIBRARY_PATH=/usr/lib:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/usr/lib64:$LD_LIBRARY_PATH
版本回退：
mv /usr/local/openssh /tmp/openssh_20240220_bak
cp /etc/init.d/sshd /etc/init.d/sshd.bak_20240220
rm -rf /etc/init.d/sshd
rpm -e openssh --nodeps
rpm -e openssh-server --nodeps
rpm -e openssh-clients --nodeps
yum安装系统自带版本：
yum -y install openssh openssh-server openssh-clients
systemctl restart sshd
