ubuntu下makeinfo/texinfo 安装的解决办法

环境: ubuntu 16.04

sudo apt-get install makeinfo

提示找不到包
搜了一圈资料，发现makeinfo其实就是texinfo

sudo apt-get install texinfo

还是找不到包，换了几个源，阿里的 华科的，都不行，最后换了清华的源，OK了

更改软件源：

sudo gedit /etc/apt/sources.list

更改为清华源：

# deb cdrom:[Ubuntu 16.04 LTS _Xenial Xerus_ - Release amd64 (20160420.1)]/ xenial main restricted
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted

deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security universe
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security multiverse

再次安装 texinfo

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install texinfo

安装成功。
