I’m trying to install ROS melodic on the Intel Edison. I got the error:
1 2 3 |
sudo apt-key adv --keyserver hkp://ha.pool.sks-keyservers.net:11371 --recv-key 421C365BD9FF1F717815A3895523BAEEB01FA116 Executing: /tmp/apt-key-gpghome.wzslgbT6vn/gpg.1.sh --keyserver hkp://ha.pool.sks-keyservers.net:11371 --recv-key 421C365BD9FF1F717815A3895523BAEEB01FA116 gpg: keyserver receive failed: Server indicated a failure |
So I found out that I can add it manually:
1 |
wget https://raw.githubusercontent.com/ros/rosdistro/master/ros.key -O - | sudo apt-key add - |
Also even if you are going to compile ROS from source you need to install
1 |
sudo apt install python-catkin-pkg |
