Install Oracle 11gr2

Hey everyone
I want to install Oracle 11gr2 on my 2 laptops: sony vaio && HP which on both of them I have installed Ubuntu 15.04, not yet upgraded to 15.10..64 bit
I have downloaded 2 files from http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html
unzip them inthe same folder, then try to run this command ./runInstaller but get error:
