Installation / usage problems

Hello guys, I tried installing/using on Ubuntu mate and Windows without success.
On Ubuntu getting some key error and on Windows 0 devices connected. Do I have to root the Android device? I m using a LG k10 LTE with Android 6.0
Do I have to do something to make it work? Followed all steps and got no success.

Hope you help me, thank you.

Hello! There is no need in root.
First of all, let's make sure that adb works fine.
What's the output when you type adb devices?
