由于旧的 CentOS6 机器和最近过期的 Let's Encrypt 根证书存在问题，我在网上找到了一个解决方案，即安装 CentOS7 的 OpenSSL-1.0.2k 补丁版本。这是我以前做过的事情，它总是能完美运行，然而，在一台特定的服务器上，当我安装此版本的 OpenSSL 时，由于某种原因，sshd 抛出了分段错误，现在它不会开始抛出此错误：
key_curve_nid_to_name: unsupported EC curve nid -1
/etc/init.d/sshd: line 128: 29710 Segmentation fault $SSHD $OPTIONS
因此，我尝试将 OpenSSL 降级到以前的版本，但由于 openssl1.0.2k 现在使用单独的包（openssl-libs），因此当我尝试降级时，只会收到此错误

手动删除 openssl-libs 也不起作用，因为几乎所有东西都依赖它，包括 yum。
有人知道我在降级时如何忽略此依赖关系吗？或者也许安装旧版本而忽略是否安装了新版本？
