What is Sugar on a Stick?

	Sugar on a Stick is a Fedora^® Spin operating system featuring the award-winning Sugar Learning Platform. Sugar on a Stick will run on any 64-bit Notebook, Laptop, or Desktop computer, with a minimum of 1GB RAM, that can run Linux, Windows or macOS, using a USB thumbdrive or stick, as a Live USB, a 32-bit computer with the TOAST version of Sugar (Trisquel on a Sugar Toast). See Trisquel On A Sugar Toast. a Raspberry Pi 2 or 3, using a microSD card, or; any computer as a virtual machine. You can use Sugar on a Stick to demo Sugar almost anywhere without disturbing the contents of the computer you use, and if people like what they see, you can install Sugar on a Stick to their hard drives or other sticks from the demo stick.

Sugar on a Stick installation instructions

MS Windows

Prepare: Download the Fedora Live USB Creator from FedoraHosted.
Download the latest Sugar on a Stick .iso file.
Load: Insert a USB flash drive (or SD Card) with 2 GB or more of free space into your computer and launch Fedora Live USB Creator to create a Sugar-on-a-Stick bootable image.
Note: Be sure to set the persistent storage slider to a non-zero value.
Boot: Insert the USB stick into a USB port on your computer. Set the option to "boot from USB" in your computer's BIOS setup, and then start up the computer.

Detailed installation instructions for Windows and booting instructions are available. There is also a guide to exploring Sugar.

GNU/Linux

Download the latest Sugar on a Stick .iso file.
Prepare: (with root user permissions at a terminal or console command line)
- Create a mount point directory: mkdir /run/soas
- Mount the .iso file to make it accessible as a disk: mount /path/to/downloaded.iso /run/soas/
  (Where /path/to/downloaded.iso is the filesystem path, or fully specified name, of the downloaded .iso file.)
  
  This is the source for the installation, and must remain mounted until the installation is complete.
- Insert a USB stick of 2 GB or greater capacity into your computer.
- With root user permissions at a terminal or console command line, use the command sudo df -Th or sudo blkid to get the USB device node name.
- Unmount the USB device filesystem:
  umount /run/media/<MyAccount>/<MyUSBdiscMountPoint>
  (The /run/media/<MyAccount>/ path is the standard mount point. Other operating systems may use /media/<MyMountPoint>.)
- (You should have the isomd5sum package installed so that the following installation script can verify the download.)

Load: Execute the following installation command, as the root user, in one command line with many options:

/run/soas/LiveOS/livecd-iso-to-disk --reset-mbr --overlay-size-mb 500 --home-size-mb 500 --unencrypted-home /path/to/downloaded.iso /dev/sd?1

The '?' in the final parameter represents the target USB device scsi drive node, such as sdb1 or sdc1, etc., and /path/to/downloaded.iso is the location and name of the .iso file.

The operating system will occupy ~960 MB, and the overlay and home size arguments, 500 and 500, were selected to fit in a 2 GB device. These may be adjusted depending on your preferences and device capacity (see LiveOS image). On a 4 GB device, one might use 1000 and 1600 for the size arguments.

The installation transcript should look something like the following:

[<user>@<system> <working directory>]$ sudo /run/soas/LiveOS/livecd-iso-to-disk --reset-mbr --overlay-size-mb 500 --home-size-mb 500 --unencrypted-home /<path to>/Fedora-SoaS-Live-x86_64-30-1.2.iso /dev/sdc1

Boot: Insert the USB stick into a bootable USB port on your computer. Set the option to "boot from USB" in your computer's BIOS setup, and then start up the computer.

To create more Sugar Sticks on other 2 GB or greater USB or SD devices, while running Sugar on a Stick, one may run the Terminal Activity, and execute this command as the root user:
livecd-iso-to-disk --reset-mbr --overlay-size-mb 500 --home-size-mb 500 --delete-home --unencrypted-home /run/initramfs/livedev /dev/sd?1

Replace /dev/sd?1 with a new device node for the second USB/SD device that you want to load with Sugar on a Stick.

Detailed installation instructions for GNU/Linux and booting instructions are available. There is also a guide to exploring Sugar. GNU/Linux users may also want to install the Sugar packages on their favorite distro, apart from Sugar on a Stick.

Apple Mac OS X

The instructions below are based on the Ubuntu Web page at <http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-mac-osx>.

Prepare: These instructions are for 32-bit and 64-bit processors.
Download the latest Sugar on a Stick .iso file.
Load:
Here is a simple way to load a bootable USB on a Mac.
1. Enter the Terminal: /Applications/Utilities/Terminal.
2. Type diskutil list. You should see all the disk drives you have inserted into your computer.
3. Insert the disk drive to which you want to write Sugar on a Stick.
4. Type diskutil list again. You should see that your USB drive has been added to the list. If not, wait a while and repeat.
5. Type hdiutil convert -format UDRW -o <Sugar on a Stick image file>.img <Sugar on a Stick image file> to convert the image into a bootable format.
6. Type sudo diskutil unmountDisk <device name> to unmount the disk (it will not be ejected).
7. Type sudo dd if=<Sugar on a Stick image file>.img.dmg of=<device name> bs=1m. sudo will ask for your password, and then dd will start writing the disk file.
8. When dd finishes writing the disk file, type sudo diskutil eject <device name>.
Boot: Insert the USB stick into a USB port on your computer, then reboot and press and hold the Option key while rebooting. You should see a list of all the EFI-recognizable USB drives that can be bootstrapped. If Sugar on a Stick is not one such drive, it cannot be bootstrapped: you need rEFInd (a fork of rEFIt).

Have a MacBook? Consider these options:

MacBook Persistent SoaS v5 USB EFI Boot

Bootable CD of Trisquel 4.5 for MacBook Air

See other installation variations at Sugar Creation Kit

Burning a CD from an .iso file on a Mac

Alternative installation instructions for Mac OS X. Also, these older installation instructions and booting instructions may be consulted.
There is also a guide to exploring Sugar.

Advanced users

Do you have an OLPC XO?

Upgrade to the latest olpc:Releases from OLPC (which may require a developer key).

Experiment with Updating XOs to the latest Sugar on a Stick release.

Some alternate installations

Once you download, and then burn or load a Sugar on a Stick (SoaS) .iso file, and boot it, the running Fedora 34 SoaS Live CD/USB may be used to install Fedora with Sugar to a hard disk or a 4 GB USB stick with the liveinst command.

- You start with a SoaS LiveOS image, and then load an uncompressed version onto the hard disk or USB stick.

Want to contribute to Sugar on a Stick?

You're in the right place! This page is a contributors portal to the project, and contains everything you need to get started in becoming part of the Sugar on a Stick community.

New contributors start here!

Welcome! We're excited that you want to help us bring the Sugar Learning Platform to children around the world. No prior experience with computers or educational technology is required - in fact, we actively encourage a diversity of backgrounds, ages, and perspectives. See the Joining Sugar on a Stick page for instructions on how to get started.

What can you do?

There are three main ways you can contribute to the Sugar on a Stick community. We work closely with our upstreams, Sugar Labs and the Fedora Project.

Get Activities on the Stick

We're always looking for help with all aspects of the Sugar on a Stick release process. Here are a few things you can do:

Test Sugar on a Stick and help us find bugs and think of ways the project could be better. When you find a bug or think of an enhancement, file a ticket! No technical experience required.
Help make it easier for others to test Sugar on a Stick by writing test cases. If you've run a test case, you can write a test case.
Fix a bug or add a feature to an existing Activity, to sugar-core itself, or to Sugar on a Stick. See How to fix an Activity bug and How to fix a sugar-core bug to get started. Basic Python programming skills - or the desire to learn - are all that's needed.
Package Sugar Activities for Fedora. If you're a Fedora Packager or want to become one, help in this area is something we desperately need - it's a trickier thing to learn, but rewarding once you get the hang of it.
Review Activities for inclusion in the build - check submitted Activities against our Sugar on a Stick/Activity Criteria and help us choose what gets included in the next release! No prior experience needed.
Have an idea for a technical feature that isn't an Activity? Check out our feature process.

Get Sticks into Schools

Deployments all over the world need many different types of help as they work through the Sugar on a Stick deployment process - we need help building resources for all deployments to use, supporting those deployments, and helping new deployments start, as well as gathering stories and feedback from deployments so that we can make the next version of Sugar on a Stick even better.

Some things you can do to help:

"It's a wiki: Edit away!" is often said in open source communities. Almost nothing is set in stone and can't be undone. So if you've got ideas how to make instructions clearer and more accessible, just go for it!
We produce official documentation such as the Creation Kit or the Customization Guide. If you've an idea how to make them better, why don't you jump in and create a patch? Creating these nifty text files is simple - instructions live in the Documentation SOP.
Unofficial documentation for unsupported workarounds for installation and customization need to be edited, tested, and submitted for approval for official support. Check them out and leave comments and improvements; just jump in and edit the page.
Interested in starting a deployment or helping a specific one (with anything from pedagogical design to technical support to funding logistics)? Introduce yourself on the deployment lists for Sugar Labs and One Laptop Per Child and we'll get you connected with some teachers on the ground.
We're looking for some people to help us assemble tools for our support team to use. Email the Sugar on a Stick mailing list if you're interested.

Get Contributors

Contributors are the lifeblood of the Sugar on a Stick community - we work hard to bring a playful mindset of teaching, learning, and meaningful work to the children we aim to reach, and we aim to keep that mindset in our own work and community as well. Welcoming and teaching new contributors or all types, building the resources they need, and teaching them how to empower others in their turn is one of the most important things you can do; it is everyone's responsibility to help build our community, one person at a time.

Some things you can do:

Edit this page and Joining Sugar on a Stick. Is there something we could do to make the "getting started" process easier? You don't have to ask permission to edit; just do it!
Help us fill in our remaining task-starter pages: Sugar on a Stick release process, How to fix an Activity bug, How to fix a sugar-core bug, and Sugar on a Stick deployment process/
Point out starter tasks on OpenHatch - fill in questions and ideas for beginner jobs, and point newcomers towards them.
Watch for introductions on the mailing list, and send welcome emails to new contributors (copy the list, so we can see what advice a newcomer has gotten so far).
Hang out with us on IRC: #sugar. This is where the IRC Activity starts off. Help new joiners past initial questions and provide instant help!

Meetings

Communication through the Sugar on a Stick mailing list has replaced regular meetings.

We once had weekly meetings on IRC - see Sugar on a Stick meetings for more information, including logs from past meetings.

Related work

While the projects listed below are not part of Sugar on a Stick, we watch them closely and try to work with them when possible (or at least we're trying to learn!)

For deployments lacking easy Internet access, one can turn a computer into a Sugar on a Stick Creation Station. The Sugar Creation Kit includes the materials you need to create Live USB sticks sticks and to install additional Activities, along with documentation and previous versions of Sugar on a Stick.
Older portable Sugar distributions based on other Linux distributions .
The undiscoverable is an unofficial FAQ for tips, tricks, and solutions to common problems that may otherwise be tricky to find. These are being considered for inclusion in the official SoaS documentation.
