“sudo update-grub”不起作用

Question

当我跑

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：

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

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

Answer 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

到

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0

也就是说，每一行应该只有一个选项。另外，在注释掉的行中，在#没有空格的地方插入一个空格是个好主意。

Answer 2

问题之一就在这个区块中：

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"

文件中的每一行应该有一个变量。

但是，也可能存在其他问题，因为错误消息完全是另一回事。尝试这个，然后更新你的问题。
