尝试安装 Python 2.7 后更新时出现错误?

尝试在我的 Ubuntu 17.04 中安装 Python 2.7 之后:

$ sudo apt-get install software-properties-common
$ sudo add-apt-repository ppa:fkrull/deadsnakes

每当我运行更新时,我都会开始收到错误:

$ sudo apt-get update

sudo apt-get update

知道原因吗?如何解决?

我猜测这些是错误:

  404  Not Found

电力ppa:fkrull/deadsnakes购买权 (Launchpad 链接) 仅支持 Ubuntu 16.04 (Xenial) 之前的版本。它根本不提供 17.04 (Zesty) 的任何软件包。

您必须再次删除该存储库,它与您的 Ubuntu 版本不兼容。

如果你使用 添加了存储库sudo add-apt-repository ppa:fkrull/deadsnakes,则可以使用以下命令轻松地将其再次删除:

sudo add-apt-repository --remove ppa:fkrull/deadsnakes

但是,17.04 已经预装了 Python 2.7:http://packages.ubuntu.com/zesty/python

无论如何,弄乱系统的 Python 版本是危险的,因为如果您不小心删除了其中一个预装的 Python 版本或将其替换为不兼容的版本,它很容易破坏许多重要的应用程序。 保持原样就行了。
