linux – 如何在运行apt-get upgrade后避免GRUB错误 – ubunut

我在EC2上运行ubuntu 14.04

运行apt-get升级后

我被提示屏幕,要求我重新安装GRUB引导装载程序

The GRUB boot loader was previously installed to a disk that is no longer present,or whose unique identifier has changed for some reason. It is important to make sure that the installed GRUB core image stays in sync with GRUB modules and grub.cfg. Please check again to make sure that GRUB is written to the appropriate boot devices.

以下提示是

A new version of /boot/grub/menu.lst is available,but the version installed currently has been locally modified.

1. install the package maintainer’s version
2. keep the local version currently installed
3. show the differences between the versions
4. show a side-by-side difference between the versions
5. show a 3-way difference between available versions
6. do a 3-way merge between available versions (experimental)
7. start a new shell to examine the situation

同样的问题在这里：

谢谢 ！！

解决方法

这个 located here目前有一个错误,它也是12.02 LTS为 seen here.Anders Hall错误报告底部列出的步骤适用于14.04 LTS 64位(HVM)AMI(ami-d05e75b8)在US-EAST-1)：

$sudo apt-get update
$sudo rm /boot/grub/menu.lst
$sudo update-grub-legacy-ec2 -y
$sudo apt-get dist-upgrade -qq --force-yes
$sudo reboot

重启后,14.04.2 LTS升级到14.04.3 LTS和sudo apt-get update&& sudo apt-get upgrade返回0个新包.
