由于 python3-minimal 和 language-gnome-selector 无法安装任何东西

我正在尝试在我的环境中安装 python3（和 python2），但我一直收到以下问题：

sudo apt-get install python3

我尝试用不同的方法修复这个问题，但每次都遇到同样的问题。感谢您的帮助。

编辑：我运行了命令

sudo apt remove python3

尝试删除 python3 但出现以下错误：

编辑 2：尝试通过以下方式安装 python3.10-minimal：

sudo apt-get install python3.10-minimal

并收到以下错误：

答案1

当你逐行阅读原始错误消息时，你会发现这些行。所有其他错误——不管怎样——都是从这个原始错误中产生的：

Setting up python3-minimal (3.10.6-1~22.04) ...
/var/lib/dpkg/info/python3-minimal.postinst: 5: py3compile: not found

这里的关键是py3compile: not found。该py3compile模块由 22.04 版软件包提供python3.10-minimal。

  • 软件包python3.xx-minimal名称随 Ubuntu 的不同版本而变化。通过查看依赖项找到适合您的 Ubuntu 版本的软件包python3-minimal

修复该问题需要两个步骤。

  1. 安装（或重新安装）你的python3.xx-minimal软件包
    sudo apt install python3.10-minimal
    或sudo apt install --reinstall python3.10-minimal

  2. 将新安装的软件包的 apt-marking 从 更改auto为manual。
    sudo apt-mark auto python3.10-minimal
