当我通过“apt upgrade”升级我的 16.04 服务器（由于 Intel CPU 错误）时，安装停止并显示以下内容：
Processing triggers for libc-bin (2.23-0ubuntu9) ...
Processing triggers for man-db (2.7.5-1) ...
dpkg: error processing package man-db (--unpack):
subprocess installed post-installation script was killed by signal (Segmentation fault)
dpkg: error: error executing hook 'if { test "$DPKG_HOOK_ACTION" = add-architecture || test "$DPKG_HOOK_ACTION" = remove-architecture; } && test -x /usr/share/pkg-config-dpkghook; then /usr/share/pkg-config-dpkghook update; fi', exit code 11
E: Sub-process /usr/bin/dpkg returned an error code (2)
之后，我在命令行上执行的所有操作都显示“分段错误”。我不得不重置硬件，但数据中心的人说它无法启动，并为我激活了救援系统。现在我可以访问文件系统，但不知道该怎么做才能让它再次启动。
有什么提示吗？
dpkg.log 的最后几行：
