Ubuntu18.04配置 ROS2 dashing+ gazebo9 + Turtlebot3

预备工作

1.换源

# 首先备份源列表
$ sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup

# 打开sources.list文件
$ sudo gedit /etc/apt/sources.list

# 在文件最前面添加阿里云镜像源
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

# 刷新列表
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install build-essential

2.配置Hosts

输入 sudo vim /etc/hosts，在最后添加

$ 199.232.69.194 github.global.ssl.fastly.net
$ 185.199.111.133 raw.githubusercontent.com

注意：不要添加 140.82.112.3 github.com ，会影响后续安装
