我正在运行 ubuntu 服务器版本 10.04 LTS。我今天在服务器上执行了“sudo apt-get upgrade”，但失败了，并显示以下信息：

知道如何修复这个问题吗？
答案1
关键错误是这样的：
update-initramfs: Generating /boot/initrd.img-2.6.32-318-ec2
Could not find postinst hook script [update-grub].
Looked in: '/bin', '/sbin', '/usr/bin', '/usr/sbin'
所有其他错误都源于此。
dpkg 似乎想要运行 update-grub，但它在你的主机上不可用。在我的主机上，我有
$ which update-grub
/usr/sbin/update-grub
$ dpkg --search /usr/sbin/update-grub
grub-pc: /usr/sbin/update-grub
$ apt-cache policy grub-pc
grub-pc:
Installed: 1.98+20100804-5ubuntu3.3
Candidate: 1.98+20100804-5ubuntu3.3
Version table:

根据您的硬件，您可能安装了不同的 grub-* 包：
$ apt-file -x search '/usr/sbin/update-grub$'
grub: /usr/sbin/update-grub
grub-coreboot: /usr/sbin/update-grub
grub-efi-amd64: /usr/sbin/update-grub
grub-efi-ia32: /usr/sbin/update-grub
grub-ieee1275: /usr/sbin/update-grub
grub-pc: /usr/sbin/update-grub
您几乎肯定安装了上述软件包之一。使用dpkg --search /usr/sbin/update-grub找出是哪一个，然后apt-get --reinstall install重新安装它。
