Can't Install CLI on Conduit AEP

Hi there,

Sorry if this is a stupid mistake, I’m very new to all of this. I’ve been trying to setup the basic station using the walkthrough here:
https://www.thethingsindustries.com/docs/gateways/multitechconduit/lbs/
And to do so need to install the CLI, I’ve tried following this:
https://www.thethingsindustries.com/docs/gateways/lora-basics-station/cups/
But when I SSH the linux commands into it it can’t find the commands. Am I using this correctly/can anyone help me find what’s wrong?
Thank you for your time.
Edit: Forgot to actually say that when inputing the linux commands putty returns that it can’t find the ‘snap’ command.
