I was following this tutorial to create forms in joomla. for this, I had to download sourcerer (which enable you to place php and html right into your content), but when I installed it, I got this error in joomla extension manager :
This extension is no longer supported on Joomla! 3.0.1. Please update to a more recent version of Joomla!: v3.1.0 or higher.
I appreciate if someone could tell me how to upgrade joomla 3.0 to 3.1 in ubuntu 12.04.
thanks,
You should be able to use the 1 click update feature that is built into Joomla.
In the Joomla backend go to Components >> Joomla! Update
On this page it should show you an available update. More information about this can be found at the following link:

Hope this helps
