I'm using Ubuntu Core for the first time, running a RocketChat server on a Raspberry Pi 3.
In order for anyone outside my home network to be able to use it, I'm trying to install ngrok per instructions in https://github.com/RocketChat/Rocket.Chat.RaspberryPi:
curl https://dl.ngrok.com/ngrok_2.0.19_linux_arm.zip -o ngrok.zip unzip ngrok.zip cd ngrok ./ngrok http 3000
However, I just get this:
-bash: curl: command not found
I've been trying to install either curl or ngrok, and failing at both.
Can I only install things that exist in the snap catalogue? How do I solve this? Where can I read more?
Edit: OK, so I can only install snaps, right? Is there any other good solution for anyone outside of my home network to access the RocketChat server?
