删除python后如何修复未满足的依赖项？

  • 772

我为安装应用程序而苦苦挣扎。在评论中的某个地方，有人说我变得残忍并且做了rm -rf /usr/lib/python2.7，然后我也做了同样的事情。在那之后我sudo apt purge python2.7-minimal现在我的系统完全崩溃了，例如当sudo apt upgrade我得到：

当我发布时，sudo apt-get -f install我得到：

我现在该怎么办！？我怎样才能修复我毁了的东西！？

  1. 基本系统服务（如 apt）依赖于 Python，因此您的系统现在很可能已严重损坏。

    你有两个选择：

    • 您可以使用 dpkg 手动重新安装每个 python 包
    • 您可以备份数据并进行全新安装。

    对于熟练的用户来说，第一个选择可能是快速且相当容易的。对于大多数普通用户来说，第二种选择可能更快、更容易。

    如果您可以访问一些运行良好的 ubuntu VPS，则可以解决此问题：

    apt download python2.7-minimal libpython2.7-stdlib python2.7

    然后，您必须使用以下命令将基本文件复制到您自己的系统中：

    sudo scp you@yourserver:/usr/lib/python2.7/*.py /usr/lib/python2.7/
sudo scp -r you@yourserver:/usr/lib/python2.7/plat-x86_64-linux-gnu /usr/lib/python2.7/
sudo scp -r you@yourserver:/usr/lib/python2.7/logging /usr/lib/python2.7/
sudo scp -r you@yourserver:/usr/lib/python2.7/encodings /usr/lib/python2.7/

    然后你应该使用 dpkg 来安装 python：

    sudo dpkg -i python2.7-minimal_2.7.12-1ubuntu0~16.04.2_amd64.deb libpython2.7-stdlib_2.7.12-1ubuntu0~16.04.2_amd64.deb python2.7_2.7.12-1ubuntu0~16.04.2_amd64.deb

    然后你应该让 apt 自己处理所有事情：

    sudo apt-get install -f

    然后您可以验证 apt 是否正常工作：

    sudo apt upgrade
