Hello and welcome to LinuxQuestions,
You'll have to keep some things in mind when posting on LQ, first is that we are all volunteers and although we are very eager to help anyone out, there might be times when there are not so many online. One of those moments is today apparently since in a big part of the world we're celebrating Mother's Day.
So, please have a little patience, I'm sure someone will help out soon.
Second and also very important thing is that when you say that a command is failing to execute, please post the exact command you issued and the errors you get. The more information you give us, the sooner someone will be able to help you.
