如何使用 apt-get 在我的 Ubuntu 12.04 服务器上重新安装 python？

因为我完全搞砸了我的 python 安装，所以我手动删除了所有 python 文件并现在尝试重新安装它。

当我输入时apt-get install --reinstall python2.7，出现以下错误消息：

0 to upgrade, 0 to newly install, 1 reinstalled, 0 to remove and 0 not to upgrade.
3 not fully installed or removed.
After this operation, 0 B of additional disk space will be used.

我该如何恢复呢？

编辑：根据 kubahaha 的建议，我尝试了

# dpkg -P python2.7

由于依赖关系，它无法正常工作。这确实删除了软件包：

# dpkg -P libapache2-mod-wsgi libpython2.7 python2.7

但当我尝试时：

# apt-get install python2.7 libapache2-mod-wsgi libpython2.7

我收到此错误信息：

/var/lib/dpkg/info/python-minimal.postinst: 4: /var/lib/dpkg/info/python-minimal.postinst: python2.7: not found                                                                         
dpkg: error processing python-minimal (--configure):

Errors were encountered while processing:

dpkg/apt 在我看来非常脆弱，因为一旦系统处于不良状态，它们似乎永远无法恢复到良好状态。

答案1

清除它然后重新安装

  1. sudo dpkg -P python2.7
  2. sudo apt-get install python2.7
