Make sure you set remote location correctly. What does Git service you use? Is it GitHub or something other?
To check did you set remote location correctly, execute git remote -v in project directory (in same directory you did git push live master).

  • git remote -v

If you use GitHub, output should be like one of this two:

Example output 1 - Remote listing - Git
live (fetch)
live (push)
Example output 2 - Remote listing - Git
live (fetch)
live (push)

In case of first output, you should be asked for username and password once you try push. For second, make sure you have set up SSH keys correctly. If you don’t have SSH key, you can follow GitHub guide to do so.
If you use GitHub and don’t match above pattern, you made some mistake. Also, once again, make sure you typed your username and repo name correctly.

thanks a lot xMudrii for your response , but can you tell me if my thinking is correct or not :
when i added live brunch i gave it the path on the Ubuntu hosting server like this :
git remote add live root@x.x.x.x:/opt/adviser.git where x.x.x.x is Ubuntu hosting server IP Address
so when i typed git remote -v i get :
live root@x.x.x.x:/opt/adviser.git (fetch)
live root@x.x.x.x:/opt/adviser.git (push)
origin (fetch)
origin (push)
is that correct , i add remote brunch with my hosting server path depend on this link
please help , i need any idea that help me ....

This article will teach you how to use Git when you want to deploy your application. While there are many ways to use Git to deploy our application, we'll focus on the one that is most straightforward.

Hello there.

It should be correct. In case of Hooks, this is how you want to do it.
First I would verify, do you have access to Ubuntu Server from Git Bash. To do so, use ssh command:

  • ssh root@droplet-ip

If that doesn’t show error (for example Permission denied (publickey).), that means this part is OK.
However, if error appears, make sure you have configured correctly SSH key on server and on client.

In case this is not a problem, make sure you created repository on Ubuntu Server correctly.
You could use How To Use Git Hooks To Automate Development and Deployment Tasks instead of DO tutorial you linked in answer, as this is newer.

Git is a very robust and mature version control system that has seen great adoption in recent years. One of git's great features is its ability to use "hooks" to call arbitrary scripts when certain git events occur. In this guide, we'll discuss the general idea behind git hooks, talk about how to work around some of its inconsistencies, and demonstrate some implementations that you can use in your development process.

yes, error is Permission denied (publickey)
i can connect to server from putty and ssh key is accepted
but when i connect from git bush , i get this error ..
what can i do ? i think my ssh keys configuration is correct ..
when i use this command :

i save my private key as c/Users/DELL/.ssh/id_rsa but it dose not work , what can i do ??
i appreciated your help ..
this is my first experiment as web developer

  • Are you sure you have your keys in right location?
    Above output is indicating that it can’t find your key. Make sure you have it in C:\Users\DELL\.ssh\id_rsa. Also make sure that key is called id_rsa and not something other.

    As a last resort, you can try generating new key, directly from, Git Bash and adding it to server authorized keys.
    You can follow steps from Initial Server Set Up - Step 4 tutorial. You will have to copy key manually using Putty.

    When you start a new server, there are a few steps that you should take every time to add some basic security and give you a solid foundation. In this guide, we'll walk you through the basic steps necessary to hit the ground running with Ubuntu 16.04.

For The access Denied Issues And git username , password

I had this problem too but managed to solve it, the error is that ur computer has saved a git username and password so if you shift to another account the error 403 will appear. Below is the solution
For Windows you can find the keys here:

control panel > user accounts > credential manager > Windows credentials > Generic credentials

Next remove the Github keys.
