When you are not using Linux everyday, and some how your linux system crashed and have to rebuilt the whole system along with all those tools you used, you will find yourself all over the internet trying to find solutions. That's exactly happened to me this week. So, thought to document some of those trouble shootings so that I can resolve quick in future:
