配置内核 make menuconfig时报错 Unable to find the ncurses libraries or the required header files.

*** Unable to find the ncurses libraries or the
*** required header files.
*** ‘make menuconfig’ requires the ncurses libraries.

*** Install ncurses (ncurses-devel) and try again.

make[1]: *** [scripts/kconfig/dochecklxdialog] Error 1
make: *** [menuconfig] Error

执行sudo apt-get install libncurses*后提示
然后更新安装包：sudo apt-get install update:
然后不能更新包，检查后发现没有联网，然后联网后，还是同样的问题
下一步，更新Ubuntu的 ‘ 源’ 换成国内的 ’源‘‘。换成国内的源之前先要备份之前的源：
1,sudo cp /etc/apt/source.list/ /etc/apt/source.list.bak
2, vi /etc/apt/sources.list
把原来的官方源全部删除，替换成下面的：

deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse
保存退出
再更新： sudo apt-get install update
成功后，
再执行 sudo apt-get install libncurses*
执行成功后
再执行：sudo apt-get install ncurses
最后再执行 make menuconfig 配置内核 成功弹出菜单
