sudo: add-apt-repository: command not found

admin

问题：
安装jdk1.8，会出现如下报错：add-apt-repository: command not found

1. nm_svr01@ubuntu:~/MT8788_9.0/mt8788_v5.196$ sudo add-apt-repository ppa:openjdk-r/ppa
   
2. sudo: add-apt-repository: command not found

复制代码

解决方法：
add-apt-repository 命令是software-properties-common包的一部分，因此安装这个包就OK了

1. sudo apt-get install software-properties-common
   
2. sudo apt-get update

解决完成：

1. nm_svr01@ubuntu:~/MT8788_9.0/mt8788_v5.196$ sudo add-apt-repository ppa:openjdk-r/ppa
