I just added some contents from allready existing 5 minutes guide to make it 2 mins and work on Lucid. 🙂
Before i start you need to have 2 things allready done,
1. $ apt-get install bzr
2. A launchpad account.
3. Your public key submitted at launchpad.
It means create a key is you don`t have allready
$ ssh-keygen -t rsa
you will see in /home//.ssh/rsa.pub created paste its content there.
4. bzr lp-login john.doe  <replace it with your username>
Adding your own info
$ bzr whoami "John Doe <john.doe@gmail.com>"
You can check what identity is stored in Bazaar’s configuration:
$ bzr whoami
john.doe
Starting New project
bzr init-repo myproject
cd myproject
bzr init trunk
cd trunk
Adding Files
bzr add hello.txt
and then commit, which saves a snapshot of all versioned files:
bzr commit -m “Added first line of text”
Pushing your branch on Launchpad
Replace john doe with your username.
bzr push bzr+ssh://bazaar.launchpad.net/~john.doe/+junk/myproject
your done.
Pushing the changes in existing branch.
bzr push
