Error cannot execute binary file when trying to run elasticsearch after installation

[CrisRus (Cristobal)]

Hello,
when trying to install Elasticsearch 7.5, I get the following error mentioned in the subject
I have just followed the instructions here:
https://www.elastic.co/guide/en/elastic-stack-get-started/7.5/get-started-elastic-stack.html#linux

So, I run the following commands

• curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.5.0-linux-x86_64.tar.gz - No problem
• tar -xzvf elasticsearch-7.5.0-linux-x86_64.tar.gz - No problem
• cd elasticsearch-7.5.0 - No problem
• ./bin/elasticsearch - I get the following error: ./bin/elasticsearch-env: line 71: /elasticsearch-7.5.0/jdk/bin/java: cannot execute binary file: Exec format error

I don't understand because I have openjdk version "1.8.0_03-Ubuntu that seems to be compatible and also Ubuntu 16.04.3 LTS with Kernel Linux 4.10.0-28-generic and x86 as Architecture. All those seem to be compatible according to Support Matrix web page ( https://www.elastic.co/es/support/matrix#matrix_jvm )

Could someone give a tip about what is happening?

Thanks and regards,

It seems, that the java bundled with Elasticsearch cannot be executed. Can you try to set JAVA_HOME environment variable to your openjdk installation?

Apart from that, is this any special hardware architecture, where Elasticsearch is running on?
