我尝试使用终端中的此命令卸载 Ubuntu 20.04 中的系统的 python 3.8。
列出默认位置中的所有 Python 版本
ls /usr/bin/python*
仅删除 python3 包 sudo apt-get 删除 python3.8
加上它的依赖包
sudo apt-get remove --自动删除 python3.8
加上 python3 的配置和/或数据文件
sudo apt-get purge python3.8
python3.5 及其依赖项的配置和/或数据文件
sudo apt-get purge --自动删除 python3.5 ), 我在 Github 中得到这个命令，它删除了包括终端在内的许多应用程序，我在这个操作系统中安装了 python 3.7.7。我有什么办法可以解决它吗？
答案1
Python 3.8 是操作系统的一部分，许多工具都依赖于它。
当您从系统中删除 Python 时，您也会删除这些工具。
如果您使用的是桌面版和我认为你会，您将无法启动到桌面，但系统应该启动到 CLI 模式。登录并从中
删除您安装的 Python 版本/usr/local/lib//usr/local/bin/
确保您的网络已启动。
ip -br add
它应该返回有关接口及其状态的信息。由于诸如此类的网络工具网络计划和网络管理器依赖于 python，它们也会被删除。
启用端口：
sudo ip link set dev {port label} up
如果你有 dhcp 服务器：
sudo dhclient
如果您使用静态 IP：
sudo ip addr add {IP address}/{mask in CIDR} dev {port label}
sudo ip route default via {gateway IP}
sudo systemd-resolve --set-dns=8.8.8.8 --interface={port label}
如果您输入了正确的信息，您应该可以访问互联网。
现在让我们重新安装您的命令将删除的所有软件包：
