我安装了 Python 2.7.15rc1，当我将 python 符号链接临时更改为 Python3 并改回时，出现了一些问题。
现在，当我尝试通过 apt 进行更新时。
sudo apt update -y && sudo apt upgrade -y
这就是我得到的。

答案1
您的输出显示此错误：
pycompile：未找到
pycompile由提供Python 语言的最小子集（版本 2.7）或者python-minimal更准确地说libpython2.7-minimal
请阅读这里。
要修复此问题，您需要重新安装libpython2.7-minimal或python-minimal在终端中运行以下命令：
sudo apt install --reinstall libpython2.7-minimal
或者：
sudo apt install --reinstall python-minimal
