I want to thank Andrew Ruthven and Thomas Lange for responding so quickly and being very helpful (it seems my replies to the threads aren't going through, probably a mistake on my part)
I am attempting to include the ROS repos to install packages from there on my client. I added entries to /etc/fai/apt/sources.list. Am I mistaken? Also, can I use the following command to add the keys? sudo apt-key adv --keyserver hkp://ha.pool.sks-keyservers.net:80 --recv-key 421C365BD9FF1F717815A3895523BAEEB01FA116 And I tried to run a bash script I wrote to download miniconda and run it to install it, but even chmod +x responds with permission denied. Would it be better for me to run these commands after the system boots for the first time? I apologize for these newbie questions. I am trying to learn how to work with FAI (almost out of university).
