“why installing ERPNext is so hard?”
I think for various reasons:
- code is fast evolving
- install process is not subject to automated testing
- lots of environments and moving parts to support
- etc
Ok @clarkej Now what should i do?
I am new in this community and i am glad because you’re helping me,
i request you to take me to a clean road, it will take your some time but i’ll appreciate your efforts.
please as i told that i am stuck even installing it over a week ago. 
“i request you to take me to a clean road,”
ok in that case how about just skip the install?
Instead simply download and run the VM version.
That saves a lot of frustration I find 
My cloud won’t allow me to import OVA file, it orders VMDK file,
how can i get VMDK file of Production (Master) version?
Sorry google that so we will both know
i did but not find anything,
i’ve download ERPNext ova file, and virtualbox on my Cloud server linux 16.04 64bit,
now when i am running the server its giving me,
VT-x/AMD-V hardware acceleration is not available on your system. Your 64-bit guest will fail to detect a 64-bit CPU and will not be able to boot.
So then your vps prvider does not support hardware virtualization.
You must find one that does…really google is your friend here
