Hi I’m trying to install ROS locally in unit 12. Setting up our keys by inputing this command:
sudo apt-key adv --keyserver hkp://ha.pool.sks-keyservers.net:80 --recv-key 421C365BD9FF1F717815A3895523BAEEB01FA116

I get this error:

raphi@raphi-VirtualBox:~$ sudo apt-key adv --keyserver hkp://ha.pool.sks-keyservers.net:80 --recv-key 421C365BD9FF1F717815A3895523BAEEB01FA116
Executing: /tmp/apt-key-gpghome.GiPz7fWncL/gpg.1.sh --keyserver hkp://ha.pool.sks-keyservers.net:80 --recv-key 421C365BD9FF1F717815A3895523BAEEB01FA116
gpg: keyserver receive failed: No data

Please help if you can.
Thanks

Hello @RNathan ,

What is your OS and which distro of ROS are you trying to install?

It is important to make sure you are using the recommended OS+Distro in the ROS official docs
