python - 无法启动“软件更新程序”：无法执行子进程 /usr/bin/update-manager（符号链接链接级别太多）
问题描述
我也有这个问题无法启动“软件和更新”：无法执行子进程“software-properties-gtk”（符号链接的级别太多）。
如果我在终端中编写software-properties-gtk我将遇到以下问题
rebeen@rebeen-Precision-5520:~$ software-properties-gtk
bash: /usr/bin/software-properties-gtk: /usr/bin/python3: bad interpreter: Too many levels of symbolic links
这是我的蟒蛇

解决方案
符号链接 /usr/bin/python3 的目的地是循环的。您可以按如下方式解决。
sudo unlink /usr/bin/python3
sudo ln -s /usr/bin/python3.6 /usr/bin/python3
