  • Dextrose running in KDE Ubuntu 12.04.2
  • Note KDE has to be installed after sugar is installed to get to this view.


NEW see notes section below

Install to Hard Disk

  1. Ubuntu Startup-disk-creator will create a USB installer
  2. Boot from Live DVD
  • "Username is "ubuntu", with empty password."
Either method will run as a live CD or Install to Hard Disk
Note: Choose lightdm as desktop manager

Install KDE

  • Sugar terminal:
sudo su
apt-get install kde-full
- Select lightdm for desktop manager when asked
- Select remote (none)
  • logout/login
- Click on the round icon in the right top corner to display the Desktop Managers available in the lightdm drop-down menu and select one:
    GNOME Classic
    GNOME Classic (no effects)
    KDE Plasma Workspace
  • It appears that lightdm which is added when KDE is installed picks up Gnome also (used by Sugar)

Install GNOME

To complete the install of GNOME
  • Sugar terminal:
sudo su
apt-get install gnome
- Select lightdm for desktop manager when asked

I just wanted to give everyone a heads about something coming down the pipe:)
On of the primary frustrations that I have been hearing from the
community is their inability to easily get hardware for their
In response, we have released of an iso running Sugar on Ubuntu at
* Username is "ubuntu", with empty password.
As alway, AC's code is 100% free and open source.

What's new

* Tuned up python-dbus clears the last bug that made most activities
fail to start.
* Logs in into Sugar automatically.
* Most activities work (some will need some work, but it should not be
caused by problems in Sugar dependencies anymore, but things specific
to the activity). To be precise they start,  didn't test them in deeply
 Didn't test collaboration yet.
* General polish to make it look closer to a final product.

What fails

* Some quirks with the tamtam activities as usual, probably already
fixed in newer bundles.
* Write does not work as the gtk3 version of pyabiword or the gtk2
version of libabiword are not available in Ubuntu, so both gtk2 and
gtk3 versions of the activity are missing half of the dependencies.
* Etoys and Scratch fail, probably because squeak-vm is not the proper
version, so I'll be packaging that later as well.
* The keyboard and network sections of the CP fail, the code makes
some assumptions about being run in a xo or under fedora, resulting in
unhandled exceptions.
* Sometimes activities may fail to start if you open them right after
logging in, because something with dbus is not yet fully running.

Sweets Distribution

  • Sugar 0.94

As of 2012-03, Ubuntu does not have a complete, stable version of Sugar in the Ubuntu repositories. In particular, there is no compatible web browser.

Until this is fixed, try one of these options:

  • use Sweets on Ubuntu, see below,
  • use a virtual appliance, compatible with any version of Ubuntu, see below,
  • use the incomplete version that Ubuntu provide, see the last section below, or
  • install from Sugar source.
your ubuntu release your best options for trying Sugar
Ubuntu 12.10 use Sweets Distribution or use a virtual appliance
Ubuntu 12.04 LTS use Sweets Distribution or use a virtual appliance
Ubuntu 11.10 use Sweets Distribution or use a virtual appliance
Ubuntu 11.04 use Sweets Distribution or use a virtual appliance
Ubuntu 10.10 use Sweets Distribution or use a virtual appliance
Ubuntu 10.04 LTS use Sweets Distribution or use a virtual appliance

How to install Sweets on Ubuntu

Install packages on an Ubuntu system so that you may run Sugar.

See How to install Sweets Distribution.

How to install a virtual appliance

Install a virtual appliance based on Ubuntu:

There are other virtual appliances based on other distributions, which can be imported into virtualization software on Ubuntu.

sweets-sugar 0.94 works in Ubuntu 12.10 (unity and cinnamon)

How to install Sugar 0.90 on Ubuntu

  • NOT Recommended

There are many problems with Sugar on Ubuntu (see a list for 0.90), many of which have been fixed in a later version of Sugar, so we recommend the Sweets or virtual appliance methods above instead.

In particular, there is no compatible web browser included, though there is a workaround.

However, if you wish to to install Sugar on Ubuntu:

  • click on Ubuntu Software Center,
  • search for Sugar,
  • click on sugar-emulator or sugar,
  • click on Install,
  • if asked about other required applications, click to install.

Sugar will be downloaded and installed.

To start Sugar, click on Applications, then Education, then Sugar.

See how to create a desktop icon that runs Sugar full screen.

See Ubuntu/Previous for how to install older versions of Sugar on older versions of Ubuntu using Ubuntu Software Center.
