ubuntu16.04编译内核出现 "mkimage" command not found - U-Boot images will not be built

按照惯例没有这个东西就安装这个东西
所以: sudo apt-get install uboot-mkimage
结果说没有找到安装包，但是提供了替换的安装包：就是这个 u-boot-tools

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:i386 u-boot-tools
所以安装: sudo apt-get install u-boot-tools
