我运行一个Ubuntu的服务器版本10.04 LTS。 我今天在我的服务器上做了一个“sudo apt-get upgrade”，失败了：
Setting up linux-image-2.6.32-318-ec2 (2.6.32-318.38) ... Running depmod. update-initramfs: Generating /boot/initrd.img-2.6.32-318-ec2 Could not find postinst hook script [update-grub].

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'
所有其他的错误从那个之后。
似乎dpkg想要运行update-grub，但是它在主机上不可用。 在我的主人，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: *** 1.98+20100804-5ubuntu3.3 0 500 http://us.archive.ubuntu.com/ubuntu/ maverick-updates/main amd64 Packages 100 /var/lib/dpkg/status 1.98+20100804-5ubuntu3 0 500 http://us.archive.ubuntu.com/ubuntu/ maverick/main amd64 Packages
根据您的硬件，您可能会安装不同的grub- *软件包：
$ 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
你几乎可以肯定有一个上面的软件包安装。 使用dpkg --search /usr/sbin/update-grub找出它是哪一个，然后apt-get --reinstall install重新安装它。
