我正在更新我的 Python，但无法通过。系统建议使用 sudo apt-get -f install，但它也不起作用。我该如何解决这个问题？
$sudo apt-get -f install

确保更新您的存储库，然后更新系统文件。然后执行reinstall of python3。
（$代表您在终端屏幕上看到的命令提示符。命令是$提示符后面的内容。）：
$ sudo apt update
$ sudo apt upgrade
$ sudo apt install python3-minimal
$ sudo apt install --reinstall python3
然后从那里添加您可能需要的存储库中的其他一些包。您可以使用以下命令获取默认存储库包的列表：
$ apt-cache search "^python3" | less
