Arduino IDE does not start

When trying to boot the IDE it tells me that it can not execute the binary.
These are the messages and version of the operating system and java

j@previo:~$ arduino
/usr/local/bin/arduino: línea 35: /home/jose/Descargas/arduino-1.8.9/java/bin/java: no puede ejecutar el archivo binario: Formato de ejecutable incorrecto

j@previo:~$ java --version

Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.2+9-LTS, mixed mode)

I just tried Arduino IDE 1.8.9 with Ubuntu 18.10 and it starts for me with no problem. You might try downloading the IDE over again in case it was corrupted the first time around.
