I have some installed programs on Ubuntu on my remote server (which I have root access to it). Now I need to install a fresh Ubuntu on some other machine/server, and I don't want to go through installing all these programs and dependencies again(mysql, rails, rvm, nginx, etc...). So is there a way to capture current state of Ubuntu programs and configurations and copy it to another Ubuntu installation ?

Thanks for closing the loop on your question. Super User's purpose is to build a knowledge base here rather than a collection of links to answers elsewhere; external links often break, in which case the answer would not be useful. Please include the essential information within your answer and use the link for attribution and reference. Just a heads up, link-only answers tend to attract downvotes and are often deleted. BTW, in another day, you will be able to accept your answer to indicate that the problem has been solved. – fixer1234 – 2016-04-17T17:31:53.613
This method, using dpkg --get-selections will list every single package installed, default ones, libraries, everything. They may not match exactly a freshly installed system, and forcibly downgrading packages could be unpredictable at best – Xen2050 – 2016-04-17T21:08:24.217
