/usr/sbin/grub-mkconfig: 1: /etc/default/grub: 如果：未找到

tag-icon • tag-icon boot grub2
/usr/sbin/grub-mkconfig: 1: /etc/default/grub: 如果：未找到

当我跑步sudo update-grub2或sudo update-grub

我得到了回应

源文件 `/etc/default/grub' /usr/sbin/grub-mkconfig: 1: /etc/default/grub: 如果：未找到

但是我的/etc/default/grub文件肯定在那里。内容如下：

# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

有线索知道错误可能是什么吗？谢谢！

答案1

错误消息

/usr/sbin/grub-mkconfig: 1: /etc/default/grub: If: not found

并没有告诉你文件 /etc/default/grub未找到，表示If在该文件的第 1 行未找到该命令。这是因为If应该是注释块的一部分，即

 If you change this file, run 'update-grub' afterwards to update

应该

# If you change this file, run 'update-grub' afterwards to update

您需要编辑文件（sudoedit /etc/default/grub例如）并插入缺失的#

答案2

我遇到了类似的错误，不确定发生了什么，但是我的 /etc/default/grub 文件在最近的更新期间添加了一行：

“/etc/default/grub” 34L，1279C

位于该文件的底部，我将其注释掉，一切又恢复正常了！
