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

Question

当我运行sudo update-grub2或sudo update-grub时

我得到了回应

资源文件`/etc/default/grub‘/usr/sbin/: 1: /etc/default/grub: If: not

但是，我的/etc/default/grub文件肯定在那里。内容如下：

 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_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
#Originally...
#GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX_DEFAULT="splash radeon.si_support=0 amdgpu.si_support=1 radeon.cik_support=0 amdgpu.cik_support=1"
GRUB_CMDLINE_LINUX=""

# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

知道错误可能是什么吗？谢谢!

Answer 1

错误信息

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

不是告诉您没有找到文件/etc/default/grub，而是说在该文件的第1行没有找到命令If。这是因为If应该是注释块的一部分，

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

应该是

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

您将需要编辑该文件(例如，使用sudoedit /etc/default/grub )并插入缺少的#

Answer 2

我收到了类似的错误，不确定发生了什么，但是我的/etc/defaul/grub文件在最近的更新中增加了一行：

“/etc/默认/grub”34L，1279 C

在那个文件的底部，我把它评论掉了，事情又对我起作用了！
