我该怎么做才能修复这个错误？

答案1

您看到的只是一个警告。这意味着它只是表明默认配置设置了一个选项，而另一个选项已设置，并且它不执行任何操作。

这里没有错误。 您可以从现在起忽略警告，直到永远，这都无关紧要。

这并不意味着有任何东西损坏，它只是一个关于某些功能不再受支持的警告消息，但它不会破坏您的系统或导致问题。

答案2

@ThomasWard 说得对，这只是一个警告，可以忽略。如果您想消除该警告，请将以下内容复制并粘贴到终端窗口：

sudo sed -i 's/GRUB_HIDDEN_TIMEOUT=0/#GRUB_HIDDEN_TIMEOUT=0/' /etc/default/grub
sudo update-grub

从现在起，该警告应该会消失。
