我已经从13升级到14，并且在升级过程中发生了很多错误。现在，我无法访问root（通过su命令）或执行类似的操作sudo apt-get install something。
注意：这不是使用su或sudo时分段错误的重复。我已经尝试过那里发布的答案，但是没有用。请参阅下面的编辑1。
如果我尝试：
sudo apt-get install XXX
我收到此错误：
Errore di segmentazione (core dump creato)
Segmentation fault (core dump created)
我该如何解决这个问题？
编辑1：
我刚刚尝试aptdcon --fix-install在答案中发布：使用su或sudo时出现段错误，它返回以下结果：

之后，我尝试运行：
echo \"$(dpkg --get-selections | grep install | cut -f 1)\"
和
aptdcon --reinstall "package1 package2 package3..."
使用生成的列表，返回以下结果：

可能是您的系统上的文件已损坏。也许在升级过程中出了点问题，或者升级在完成之前就停止了（可能是由于断电或磁盘空间不足？）
分段错误是一个严重错误，在正常情况下不应该发生。
这另一个答案建议使用：
aptdcon --fix-install
然后，这可能会导致您不得不重新安装一些其他软件包-有关更多详细信息，请参见该其他答案。
在看到更新的信息之后，看起来这似乎是此处和此处提到的samba问题，在那里升级/重新安装samba可能会破坏登录名（包括sudo）。
此错误报告中对此进行了描述。
因此，您可以尝试清除所有与samba相关的软件包，然后重新安装samba（如果需要，或者将其完全删除）。特别是，您需要清除libpam-smbpass。
因为您不能使用sudo，所以您需要通过单用户模式来执行此操作，Ubuntu可以通过启动屏幕上的“恢复模式”使用它。
引用该错误报告：
- Reboot and choose the "recovery mode" from the boot selection menu
- Choose "drop into root shell" from the recovery menu
- Execute the command: dpkg --purge libpam-smbpass
