I followed these steps:

1. Open Console and change the directory

   
   

   cd /opt/

   
   



2. Extract the file

   
   

   sudo tar -xvzf ~/Downloads/jetbrains-toolbox-1.xx.xxxx.tar.gz

   
   



3. Rename the folder (not mandatory but it's easier for later use)

   
   

   sudo mv jetbrains-toolbox-1.xx.xxxx jetbrains

   
   



4. Open JetBrains Toolbox

   
   

   jetbrains/jetbrains-toolbox

   
   

If you can't open the file type sudo apt install libfuse2
