Recently, while trying to fly my drone, the system suddenly crashed on me. I was logged in to the drone through ssh and when going through the terminal it suddenly crashed and I had to reset the drone to its default settings meaning I have to reinstall Ubuntu. The problem now is that I can't reinstall Ubuntu. My install process is halted at this command "wget -qO - https://download.01.org/aero/deb/intel-aero-deb.key | sudo apt-key add -". It just gets stuck there without doing anything. I'm assuming that it can't get the update but I am not sure. Is there any reason why this may be? I know that Intel decided to discontinue the sale of the Aero but I believe files and support will be discontinued at a later date. Thank you.
Edit: The command finished running. I get a message saying
gpg: no valid OpenPGP data found.
