重新生成/ etc / default / grub
我不小心用错误的:w !sudo tee % /etc/default/grub :w !sudo tee %擦了/etc/default/grub 。 有没有办法重新生成其内容？ 原件是否可以在某处复制？
令人惊讶的是，任何软件包似乎都没有提供该文件/etc/default/grub/ 。 我使用了dpkg -S /etc/default/grub ，但它失败了。 但是，您可以从下面复制默认文件的内容。 该文件与Ubuntu 12.04和12.10相同。

这对我有用：
sudo apt-get remove --purge grub-pc sudo apt-get install grub-pc
