SSH into VM and run "git pull" using Paramiko - Python

Question

I'm trying to SSH into my VM and did perform a git pull

the SSH seems to be working fine
the git pull seem to be executed
but when I provide password, it doesn't seem to take it
Am I missing something ?

I have

import paramiko
import time
import sys
import os
import pdb

# Note
# sudo pip install --user paramiko
ip = "111.111.111.111"
un = "root"
pw = "abc"

def ssh_con (ip, un, pw):
    global ssh
    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh.connect(ip, username=un, password=pw)

def cmd_io (command):
    global ssh_cmd
    ssh_cmd.send("%s \n" %command)
    time.sleep(1)
    output = ssh_cmd.recv(10000).decode("utf-8")
    print (output)

ssh_con(ip,un,pw)
ssh_cmd = ssh.invoke_shell()
print ("SSH CONNECTION ESTABLISHED TO %s" % ip)
cmd_io("git pull")
time.sleep(2)
cmd_io(pw)

I kept getting

git pull 
Enter passphrase for key '/root/.ssh/id_rsa': 

Enter passphrase for key '/root/.ssh/id_rsa':

First create a credential.helper like: stackoverflow.com/questions/11403407/… — Hackerman

It looks like your SSH Rsa Key pair has been setup up with a pass phrase for root on 111.111.111.111. You can recreate the ssh rsa key with:

ssh-keygen -t rsa

and just leave pass phrase blank.

Semantics, but the pass phrase is not for 111.111.111.111, but for the private key on the local host. And if you recreate the ssh keys, the remote systems will need to know the new public key.
