我正在windows电脑上安装ROS2。我使用的是WSL2, Ubuntu 20.04.LTS
sudo apt install ros-foxy-desktop -y
但是结果是
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package ros-foxy-desktop
如何解决这个问题?
您需要添加正确的源代码，以便apt能够找到该包。在这里- https://docs.ros.org/en/foxy/Installation/Alternatives/Ubuntu-Install-Binary.html -你可以看到，你需要运行至少两个步骤之前安装狐狸。
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
注意:这些步骤在ubuntu 22.04上运行良好。不确定20.04
