由于 apport 错误，无法再使用 apt-get 进行安装

Question

我正在使用 Xubuntu（Ubuntu 14.04.2 LTS，64 位）Virtual Box 在 Windows 7 PC 上工作。最近，我在使用“apt-get”命令和软件更新程序时遇到了问题。软件更新程序无法下载其中一个更新 - 我已获得 2.14.1-0ubuntu3.10 并且它正在尝试安装 2.14.1-0ubuntu3.11，但失败了。

另外，当我输入任何类型的“apt-get”或“dpkg”命令时，比如“apt-get upgrade”，我得到如下错误，有人知道我能做什么吗？

我只是试图/usr/bin/pyclean在我的电脑上编译 python 文件，我用 python3 编译它，我得到了同样的错误，而当我用 python2 编译它时，没有错误。

因此，我猜您更改了系统中的某些内容，使默认的 python 版本为 python3。

您可以尝试像这样解决这个问题：

• 执行命令ls -l /usr/bin/python并查看其输出。

• 如果文件/usr/bin/python指向 python3.x ，则删除链接并将其替换为指向 python2 的链接

  sudo rm /usr/bin/python
  sudo ln -s /usr/bin/python2.7 /usr/bin/python
  

  现在 python2.7 将作为系统中的默认 python 版本恢复原状
