Can't install spotify via ssh after root

[razserv2010]

I managed to root the device STYTJ02YM V8 now I'm trying to install spotify through this guide:
https://eddiez.me/spotify-vacuum/
But when I run this command:
apt-get install -y curl
I get

root@TinaLinux:~# apt-get install -y curl
-ash: apt-get: not found

and date:

root@TinaLinux:~# date
date: invalid date ''
date: invalid date ''
date: invalid date ''

This is a different operating system. apt-get is not supported, so your guide is not applicable.

Out of curiosity: how did you root the device? Did you use this repository for it?
How do you know if you have v8 vs v7?
