‘update-grub’ 语法错误

我读过几个以前的问题，但找不到解决方案。我运行命令时，update-grub它给出了以下输出：

root@Agustin-Ubuntu:/home/agustin# update-grub
Generating grub.cfg ...
Warning: Setting GRUB_TIMEOUT to a non-zero value when GRUB_HIDDEN_TIMEOUT is set is no longer supported.

这里的问题是，在更新到 3.5.0-45-generic 版本后，Grub Customizer 没有更新，因此菜单中的条目全都乱了，而且我无法按照我想要的顺序排列它们，因为 Grub Customizer 没有效果，它显示了正确的新条目，但在我启动时它不会修改菜单。

这是我的/etc/default/grub文件：

# 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="1"
#GRUB_HIDDEN_TIMEOUT="0" 
GRUB_HIDDEN_TIMEOUT_QUIET="true" 
GRUB_TIMEOUT="10" 
GRUB_DISTRIBUTOR="`lsb_release -i -s 2> /dev/null || echo Debian`" 
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
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"

GRUB_SAVEDEFAULT="false"

我刚刚检查了我的/etc/default/grub，它看起来和你的 pastebin 中的一样，但自从默认安装 Ubuntu 14.04 Trusty Thar 以来，我也收到这个警告。

所以这对我没有帮助。结果仍然一样。我发现 launchpad 上已经有了很大的讨论。看看这里：

https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1258597

但是此链接上的注释#10显示了诀窍，如何理清事情。/etc/default/grub需要在第二行和第三行编辑该文件，如上图 launchpad 链接上的注释 #10 所示：

sudo gedit /etc/default/grub
GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=countdown
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.modeset=1"
GRUB_CMDLINE_LINUX=""

然后做：

sudo update-grub

这样就把事情理顺了...

Grub Customizer 添加或编辑文件，/etc/default/grub.d因此您需要修复的文件位于此目录中，这就是为什么您的文件没有任何问题/etc/default/grub。

此外，错误告诉您检查第 165 行，而您需要检查的文件是/boot/grub/grub.cfg.new。

因此，转到文件/boot/grub/grub.cfg.new并向下滚动到第 165 行。这是语法错误所在。在每个代码段的开头，都有一行以 开头，### BEGIN后面跟着配置文件名。这是包含您需要修复的错误的文件。

看这个详细的例子按用户@donquixote。

我已经在 pastebin 中保存了一个原始的 /etc/default/grub 文件，以应对这种情况。打开终端并执行

sudo cp /etc/default/grub ~/default-grub.bad
sudo wget "http://pastebin.com/raw.php?i=g3TMZgTP" -o /etc/default/grub 
sudo update-grub

查看原始格式的文件这里

附加建议：

您已安装了许多内核。尝试删除旧内核。您可以使用 ubuntu-tweak 或 synaptic 等程序。

答案4

您将几个命令放在了注释掉的一行上，却将最后一个命令分成了两半，放在了下一行的非注释行上，这样就搞砸了您的 /etc/default/grub 文件。“echo Debian`” GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"" 是前一个命令的一部分，必须位于同一行。
