我想将我的 Ubuntu 18.04 升级到 20.04。当我尝试这样做时，出现以下错误：
Your python3 install is corrupted. Please fix the '/usr/bin/python3' symlink.
我一直在寻找解决方案，发现可以通过以下方法解决：
sudo rm /usr/bin/python3 && sudo ln -s /usr/bin/python3.8 /usr/bin/python3
do-release-upgrade
但当我这样做时，我得到了：
bash: /usr/bin/do-release-upgrade: /usr/bin/python3: bad interpreter: No such file or directory
的输出type -a python3; file /usr/bin/python3为：
bash: type: python3: not found /usr/bin/python3: broken symbolic link to /usr/bin/python3.8
输出为file /usr/bin/python3.6：
/usr/bin/python3.6: cannot open `/usr/bin/python3.6' (No such file or directory)
我应该怎么办？
答案1
打开终端并输入：
sudo apt-get install --reinstall python3-all
sudo apt purge python3.8
sudo apt-get install --reinstall update-manager
sudo apt update

用户 Christian 评论道您的 python3 安装已损坏。请修复“/usr/bin/python3”符号链接需要/usr/bin/python3指向/usr/bin/python3.6。您需要的命令是：
sudo ln -fs /usr/bin/python3.6 /usr/bin/python3
