After the installation of the .deb file, go to "System -> Preferences -> Preferred Applications" and select Gmail. That’s it.

Ubuntu Preferred Applications for Gmail

My decision was to use git this time and give it a try. I don’t know what to expect but let’s roll.
By the time this tutorial was written, gitosis was not in the ubuntu repositories, so I had to install it manually.
After the installation was done, I was stunned how fast it was over.

But see for yourself:

Step 1
First we need to get git on our machines.

sudo apt-get install git-core

You need to do this on every machine – client and server.
From now on we can start to use all git commands. But what we really want is a server installation, so it’s not over now.

Step 2
All following steps are done on the server.
Log into your server using ssh.
In the end we will have a service running git.So it is a good idea to create a system user for that task:

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

Step 3
Also install the python set up tools for the compilation and installation of gitosis.
Yet again, another call for apt:

sudo apt-get install python-setuptools

Step 4
Now we have everything together to install gitosis. For the installation we do our first clone of the sources and immediately install them:

mkdir ~/tmp
cd ~/tmp
git clone git://eagain.net/gitosis.git    #here we fetch the sources
cd gitosis
sudo python setup.py install

Now gitosis is installed.

Step 5
In the end you have two choices:
If you use ssh logins via keyfile, then you can use the following command to fire up gitosis:

sudo -H -u git gitosis-init < ~/.ssh/authorized_keys
sudo chmod 755 /home/git/repositories/gitosis-admin.git/hooks/post-update

if you don’t have ssh via keyfile use this:

sudo -H -u git gitosis-init
sudo chmod 755 /home/git/repositories/gitosis-admin.git/hooks/post-update

You’re done!

You can validate your installation if you run following command on your client:

cd ~/tmp
git clone git@YOUR_SERVER:gitosis-admin.git
cd gitosis-admin

I’m off celebrating new year.
I hope to see you all in good health in the next decade.

The video explains the concept and in the end you’ll see it move.
This is a very interesting concept if you think of bots on microscopic scale, lust like amoeba.
The less complex mechanical parts you have in a a machine, the less likely something will brake.
