Ubuntu默认的软件源在国外,可能会造成下载软件卡顿,因此需要换源,这里我选择更换为阿里源。
1.双击Ubuntu22.04 LTS图标,在命令行中输入
# 备份原来的软件源
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
# 编辑软件源
sudo nano /etc/apt/sources.list
2.将原来的内容替换为阿里源
deb http://mirrors.aliyun.com/ubuntu/ jammy main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ jammy main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ jammy-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ jammy-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ jammy-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ jammy-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ jammy-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ jammy-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ jammy-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ jammy-backports main restricted universe multiverse
Ctrl + O保存, enter, Ctrl + X退出
3.更改后
4. 更新升级软件
在Ubuntu命令行中依次执行如下命令:
# 更新软件源
sudo apt-get update -y
# 升级所有软件
sudo apt-get upgrade -y
sudo apt update
sudo apt install locales
sudo locale-gen en_US en_US.UTF-8
sudo update-locale LC_ALL=en_US.UTF-8 LANG=en_US.UTF-8
export LANG=en_US.UTF-8
1.通过检查此命令的输出,确保已启用Ubuntu Universe存储库。
apt-cache policy | grep universe
①正常情况
②若没有看到像上面这样的输出行,依次执行如下命令:
sudo apt install software-properties-common
sudo add-apt-repository universe
2.继续执行如下命令:
sudo apt update && sudo apt install curl gnupg lsb-release
sudo curl -sSL https://raw.githubusercontent.com/ros/rosdistro/master/ros.key -o /usr/share/keyrings/ros-archive-keyring.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/ros-archive-keyring.gpg] http://packages.ros.org/ros2/ubuntu $(source /etc/os-release && echo $UBUNTU_CODENAME) main" | sudo tee /etc/apt/sources.list.d/ros2.list > /dev/null
①正常情况
②报错:curl: (7) Failed to connect to raw.githubusercontent.com port 443 after 0 ms: Connection refused
解决
sudo nano /etc/hosts
加上一行
199.232.28.133 raw.githubusercontent.com
Ctrl + O保存, enter, Ctrl + X退出
sudo apt update
sudo apt upgrade
安装桌面版
sudo apt install ros-humble-desktop
安装时间较长,慢慢等待
source /opt/ros/humble/setup.bash
echo " source /opt/ros/humble/setup.bash" >> ~/.bashrc
①通过以下命令启动一个数据的发布者节点:
ros2 run demo_nodes_cpp talker
②启动另一个终端,通过以下命令启动一个数据的订阅者节点
ros2 run demo_nodes_py listener
