I'm using this link to install git-core, gitolite and gitweb in ubuntu 12.04:
https://ao2.it/wiki/How_to_setup_a_GIT_server_with_gitolite_and_gitweb
I installed git-core by using this command: 

sudo apt-get install git-core

Then I added a new user git by using this command: 

sudo adduser \
    --system \
    --shell /bin/bash \
    --gecos 'git SCM user' \
    --group \
    --disabled-password \
    --home /home/git \
    git

Then I added repositories in /home/git 

sudo -u git mkdir /home/git/repositories

Then I moved to windows machine, and generated pub and ppk keys by using this command: 

ssh-keygen -t rsa

Then I copied pub key to ubuntu and added it to /home/<username>/.ssh/ folder.
Then I ran scp command in windows cmd: 

scp C:/Users/Ajay Kulkarni-enEXL/.ssh/id_rsa.pub 192.168.1.140:git.pub

git is the new user name in Ubuntu which I created earlier.
Output of that command was: 

You can't hack this system from external connectors like putty telnet etc.!!

Good luck with hacking this system cheers :)

Then I copied pub key to ubuntu and added it to /home/<username>/.ssh/ folder

You would actually need to add it to /home/git/.ssh/authorized_keys (with the right permission, as seen here

server$ mkdir ~/.ssh
server$ chmod 700 ~/.ssh
server$ cat ~/id_rsa.pub >> ~/.ssh/authorized_keys
server$ chmod 600 ~/.ssh/authorized_keys
server$ rm ~/id_rsa.pub

).

Test your ssh connection with

ssh -Tv git@192.168.1.140

You must be able to open an ssh session as git, before proceeding any further.

  • with right permissions? You want me to do a `chmod 777`? – Ajay Kulkarni Oct 06 '16 at 09:16
  • No: read http://stackoverflow.com/a/37626619/6309 and http://stackoverflow.com/a/13428529/6309 – VonC Oct 06 '16 at 09:26
  • There was no `authorized_keys` file in `.ssh` folder. So I directly ran `cat ~/id_rsa.pub >> ~/.ssh/authorized_keys` and changed permissions and removed `id_rsa.pub`. Then I moved to windows and executed scp command with double quotes around file path. I got this output: `ssh: C: no address associated with name` – Ajay Kulkarni Oct 06 '16 at 09:37
  • Right, the syntax is wrong. Let me check again in a bit (on my phone right now) – VonC Oct 06 '16 at 09:42
  • Okay... I tried without double quotes and `scp` asked for password. I was surprised because I had given a passphrase while key generation. Nevertheless, I gave ubuntu's password and it refused to connect. Why? – Ajay Kulkarni Oct 06 '16 at 10:11
  • @AjayKulkarni I have edited my answer. Actually, the git.pub needs to go into the git account on your Ubuntu server. – VonC Oct 06 '16 at 10:38
  • "I gave ubuntu's password and it refused to connect.": it asks you a password because you try to open a session as a user who does not exist on the server (`Ajay Kulkarni-enEXL` instead of `git`): when ssh cannot communicate authentication through public/private key, it falls back to username/password. Which does not work here since the only user registered on Ubuntu is the one your created: git. – VonC Oct 06 '16 at 10:40
