当我运行时update-grub得到以下输出：
Generating grub.cfg ...
Found linux image: /boot/vmlinuz-3.5.0-26-generic
Found initrd image: /boot/initrd.img-3.5.0-26-generic

done
为什么列出了三张图片？
我读了 ”grub 显示两次相同的 Linux 映像“ 也没有解决我的问题。
我的 /etc/grub.d/ 的内容是：
$ ls -l

答案1
我通过谷歌搜索找到了这一点：
current=`uname -r` && uninstall="" && for version in `dpkg -l linux-image* | grep ii | awk '{ print $2}'`; do if [[ "$version" < "linux-image-$current" ]]; then uninstall=$uninstall" $version"; fi; done && sudo apt-get purge $uninstall -y && sudo update-grub2
它会删除旧内核并更新 grub。这解决了我的问题。
