- 原因
- 在 ubuntu 编译了一个 OpenSSL 的源码，并执行了
sudo make install。 Ubuntu 自带的 OpenSSL 版本带有额外的补丁，包含版本信息等，但是标准的 OpenSSL 库(1.1.0 之前)是没有版本信息的。OpenSSH 在运行时链接到源码编译的 OpenSSL 库，没有这些版本信息符号
- OpenSSH 和 OpenSSL 的安装顺序是有一定限制的，可单独升级 OpenSSH，但升级了 OpenSSL 之后，需要重新编译 OpenSSH 或升级，否则不能使用 OpenSSH
- 解决方法
- 删除
/usr/local/include/openssl
- 删除
/usr/local/lib/libcrypto.*
- 删除
/usr/local/lib/libssl.*
