Uninstall Unity 2017.3.0f1 Linux Editor on Ubuntu 17.10

Hi guys,
I searched the web and the installed folder but nothing is there so uninstall
https://beta.unity3d.com/download/3c89f8d277f5/public_download.html
from ubuntu 17.10.

Code (CSharp):

1. sudo dpkg --purge ...
2. sudo apt purge ...

do not work. Since you @PJayB have posted the linked Unity version, do you have any suggestions?

 

Finding an other answer took to long, I executed the rm -rf commands one by one but I do not see why this gist I created with them should not work:
