在 archlinux 上工作，今天最后一次更新。尝试在服务器上设置一个 Web 应用程序。尝试 su 时出现错误“核心转储”，决定重新启动。重新启动后问题开始出现。
输入密码后的 ssh -vvv 输出（如有需要可以提供完整日志）：

尝试使用 -t param。
ls 输出go、cat /etc/passwd file not found、cd 和许多其他命令：command not found
不知道发生了什么，也不知道该怎么办。
另外，我可以物理访问该机器，但想留在 ssh 中（这有点困难）。
答案1
这个答案很愚蠢。
我尝试了很多不同的解决方案来解决这个问题，但答案是在登录后快速按 ctrl+c。然后，我就可以做我的事情了。
我记得我尝试安装一些 yum 包或类似的东西，一周后才发现问题（重启后没有检查服务器）。也许更新冻结了系统？不确定。
