“sudo update-grub”不起作用

当我跑步时

sudo update-grub

我收到以下错误:

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

这是我的/etc/default/grub

答案1

尝试使用 编辑文件gksudo gedit /etc/default/grub

在您的文件中,更改行

GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0

也就是说,每行应该只有一个选项。另外,在注释掉的行中,在#不存在的后面插入一个空格是个好主意。

答案2

其中一个问题出现在这个区块中:

GRUB_DEFAULT=0  #Add newline here
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=5 #Add newline here too
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` 
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX="splash quiet"

文件中每行应该有一个变量。

但是,也可能存在其他问题,因为错误消息说的是完全不同的事情。尝试一下,然后更新您的问题。

答案3

当我使用 OpenOffice Writer 而不是 pluma/gedit 编辑文件时,发生了这种情况。我猜它添加了一些奇怪的 Unicode 字符。
我用以下方法修复了它

sudo cp /usr/share/grub/default/grub /etc/default/grub
