在網上查了下，使用apt-get install uboot-mkimage時，彈出錯誤如下：

[email protected]:/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

按提示安裝u-boot-tools後，依然無法安裝或直接使用mkimage

最終在以下網站找到可以更新mkimage的地方：

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

依該網頁提示，將/proc/apt下的source.list中的源裡面加入：

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

輸入sudo apt-get update後，再敲apt-get install uboot-mkimage就安裝成功了，如下：

[email protected]:/etc/apt# apt-get install uboot-mkimage
