当尝试更新 grub 时，我遇到了同样的问题，导致更新过程无法完成：

Syntax error at line 179
Syntax errors are detected in generated GRUB config file.
Ensure that there are no errors in /etc/default/grub
and /etc/grub.d/* files or please file a bug report with
/boot/grub/grub.cfg.new file attached.
我尝试自己调试该文件，但无法确定特定错误报告的正确语法。我还尝试删除并重新安装 grub，但任何更改 grub 的尝试都会给我带来上面显示的相同错误。上述错误还阻止我更新系统或安装任何新软件包。除了几天没有更新之外，不确定是什么导致了这种行为，因为我没有对 grub 文件进行任何手动更改。
以下链接列出了 grub.cfg.new 文件的内容，希望有人可以帮助解释这个问题： https://pastebin.com/hcFxrwLD
