====== X2Go packages for Ubuntu GNU/Linux ======

Packages for Ubuntu are provided for several platforms (amd64/i386, lucid/maverick/natty/oneiric. 
From our nightly-builds on Ubuntu Launchpad we regularly copy package to the Launchpad PPA:  **[[https://launchpad.net/~x2go/+archive/ubuntu/stable|ppa:x2go/stable]]**.

Before adding X2Go's Launchpad package repository to your APT system, please make sure that you use Ubuntu's ''main'' __and__ ''universe'' repository on your Ubuntu system. The very minimal ''/etc/apt/sources.list'' must look like this. (Of course we recommend to have Ubuntu security updates enabled, explaining how to do this is off-topic here, though.):

<code>
deb http://de.archive.ubuntu.com/ubuntu <my-ubuntu-version> main universe
</code>

===== Add the X2Go repository on Launchpad to APT =====

Use the following commands to add the ''ppa:x2go/stable'' as a package source to your local system.
Before doing so, you might like to learn about [[https://help.ubuntu.com/community/AptGet|apt-get]], [[https://help.ubuntu.com/community/RootSudo|sudo]] and [[https://help.ubuntu.com/community/Repositories/CommandLine#Adding_Launchpad_PPA_Repositories|ppa]]s

Alternatively you can also use the Ubuntu [[https://help.ubuntu.com/community/Repositories/Ubuntu#Adding_PPAs | software center]].

You might have to install ''add-apt-repository'' first.

To to install ''add-apt-repository'' on Ubuntu 10.04 or 12.04:
<code bash>
sudo apt-get install python-software-properties
</code>

To to install ''add-apt-repository'' on Ubuntu 14.04 and beyond:
<code bash>
sudo apt-get install software-properties-common
</code>

Afterwards you can add our ppa:

<code bash>
sudo add-apt-repository ppa:x2go/stable
sudo apt-get update
</code>


The X2Go related packages should now be listed calling:
<code bash>
apt-cache search x2go
</code>


Congratulations, you are now able to access the X2Go packages. You may continue by installing ''x2goserver'', ''x2goclient'' or ''pyhoca-gui'' or any other of the available packages. 

For example, if you only want to install the X2Go client:

<code bash>
sudo apt install x2goclient
</code>

===== Behind a Proxy? =====
If you are on a site that uses a HTTP proxy to connect to websites on the internet, make sure you run the following commands first before adding the X2Go PPA to your APT package management system (replace ''my.proxy.server'' and ''my_proxy_port'' with your local site's proxy settings):

<code bash>
export http_proxy=http://<my.proxy.server>:<my_proxy_port>/
export https_proxy=http://<my.proxy.server>:<my_proxy_port>/
</code>
