INS-30131 Initial setup required for the execution of installer validations failed Failed to access

When I am installing Oracle Grid Infrastructure 12c Release 1 (12.1.0.1.0) I have the following error:

INS-30131 Initial setup required for the execution of installer validations failed Failed to access the temporary location

Cause: - Failed to access the temporary location

Action - Ensure that the current user has required permissions to access the temporary location

Addition details

- PRVG-1560: Temporary directory path "/tmp/" is shared on nodes  "...."

The oracle user that I am using is having access to /tmp, I made a test by creating a file there.

Any idea?

Thank you
