这里有个过于急切的菜鸟。
我一直在尝试在新安装的 Ubuntu 18.10 上更新 GRUB。
我使用 GRUB Customizer 进行大部分编辑，但它无法更新我的背景图像。
我阅读了一些有关仅编辑/etc/default/grub文件的文档。当我尝试打开 GRUB 定制器或运行时，我目前收到以下错误update-grub：
$ sudo update-grub
Sourcing file `/etc/default/grub'
Generating grub configuration file ...
/etc/grub.d/40_custom_proxy: 16: /etc/grub.d/40_custom_proxy: Syntax error: "(" unexpected
我四处寻找，找不到遇到类似问题的人，而且我是这里的新手，除了寻求帮助，我不知道下一步该去哪里。任何正确的方向、提示或技巧，对于诊断此类错误，我将不胜感激。
以下是我的默认 grub 文件，供参考：

# /boot/grub/grub.cfg.

如果您需要我添加任何其他信息，请告诉我。（所有这些以及我的背景仍然是紫色的，带有问号边框，这是以后的问题）。
编辑更多信息，更新运行 update-grub 的输出。

答案1
看来您已经多次使用过 grub/grub 定制器。
如果您还没有使用过 40_custom 文件，并且能够无错误地更新 grub，请按照以下步骤操作。
1. 使用 grub 的自定义背景..
/etc/default/grub在终端中使用以下命令打开文件
sudo -H gedit /etc/default/grub
底线之下
# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"
粘贴以下内容
GRUB_BACKGROUND="/home/nicholas/Pictures/Winbuntu_Grub.png"
保存文件并关闭。然后运行sudo update-grub并查找以“找到背景图像：”开头的文本，如果出现此文本，则背景将起作用。
例子：
$ sudo update-grub
Generating grub configuration file ...
Found background: /home/pratap/Pictures/Winbuntu_Grub.png
Found background image: /home/pratap/Pictures/Winbuntu_Grub.png
Found linux image: /boot/vmlinuz-4.15.0-34-generic
Found initrd image: /boot/initrd.img-4.15.0-34-generic
Found Windows Boot Manager on /dev/sda1@/EFI/Microsoft/Boot/bootmgfw.efi
Adding boot menu entry for EFI firmware configuration
done
$
2. 更改 grub 菜单颜色..
/etc/grub.d/05_debian_theme在终端中使用以下命令打开文件
sudo -H gedit /etc/grub.d/05_debian_theme
转到第 129 行左右并编辑内容如下
if [ -z "${2}" ] && [ -z "${3}" ]; then
# echo " true"
echo "set colro_highlight=light-blue/black"
echo "set color_normal=green/black"
fi
保存文件并关闭。然后运行sudo update-grub
重新启动才能看到更改。

无法找到确切答案。我已从实时会话重新安装了 GRUB 并退出。感谢您的关注。
