在网上查了下，使用apt-get install uboot-mkimage时，弹出错误如下：

jim@jim-vm:/etc/apt$ sudo apt-get install uboot-mkimage
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package uboot-mkimage is not available,but is referred to by another package.
This may mean that the package is missing,has been obsoleted,or
is only available from another source
However the following packages replace it:
u-boot-tools

E: Package 'uboot-mkimage' has no installation candidate

按提示安装u-boot-tools后，依然无法安装或直接使用mkimage

最终在以下网站找到可以更新mkimage的地方：

http://packages.ubuntu.com/zh-cn/lucid/i386/uboot-mkimage/download

依该网页提示，将/proc/apt下的source.list中的源里面加入：

deb http://kr.archive.ubuntu.com/ubuntu lucid main

输入sudo apt-get update后，再敲apt-get install uboot-mkimage就安装成功了，如下：

root@jim-vm:/etc/apt# apt-get install uboot-mkimage Reading package lists... Done Building dependency tree Reading state information...
