Step no: 4 of 7 | Installation configuration - Missing Optional Pre-requisite
--------------------------------------------------------------------------------
There is one or more optional unresolved issues. It is highly recommended to fix
it all before you continue the installation. You can fix it without exiting from
the installation and re-check. Or you can quit from the installation, fix it and
run the installation again.
--------------------------------------------------------------------------------
Missing optional pre-requisite
-- operating system type is not supported.
-- system glibc or kernel version not supported or not detectable
-- binutils version not supported or not detectable
--------------------------------------------------------------------------------
    1. Skip missing optional pre-requisites [default]
    2. Show the detailed info about issue(s)
    3. Re-check the pre-requisites

    h. Help
    b. Back to the previous menu
