Resolving The Problem
If you install WAS 8.5.5.8 and higher the error will not be seen.
For installing on the versions between 8.5.5 and 8.5.5.7 To bypass operating system prerequisite checking, add disableOSPrereqChecking=true to the config.ini file in IM_install_root/eclipse/configuration and restart Installation Manager
IM_install_root is directory where Installation Manager is installed.
