Plugson installation - not working.

[longpanda]

I guess "No such file or directory" mean it can not found VentoyPlugson.sh.
So the current directory . may be not in your PATH environment variable.
So please try  sudo  bash  ./VentoyPlugson.sh    or    sudo  bash  /home/xxx/xxx/xxx/VentoyPlugson.sh  (use its absolute path)
