Upgrading to 8.2
If you have a machine running update.1 (builds 650-656) or 8.1 (builds 700-715), here is how to upgrade your system to 8.2. As of November, 2008 this is the latest stable release.

8.2 (build 767)
Upgrading over the Internet
Reserve enough time for this : the process can take more than 30 minutes. If you are interrupted in the middle of an update, you can continue where you left off.
0. Make sure your XO is plugged in and turned on.
1. Backup any files you want to save. Upgrading may make some activities work differently, and may make Journal items that depend on old activities stop working.
3. Launch the Terminal activity 
. From the Terminal, type:
su - olpc-update 767
This will upgrade your system to build 767 (the latest stable 8.2 build). This will take 5-30 minutes depending on your connection speed. You should see text like this:
Downloading contents of build official-os860
Updating to version hash xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Making clean /versions/updates/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Trying irsync_pristine update from rsync://updates.laptop.org/build-official-os860
- Cleaning tree.
- Fetching contents.
- Performing incremental rsync.
Verifying update.
Installing update in /versions/{pristine,run}/xxxx
Sometimes you will get a message about irsync_pristine failing, or that "irsync_dirty" is being tried; this is normal.
If the update halts (for instance, if you lose your network connection in the middle) you will be returned to the Terminal prompt. You can repeat the command to resume the update where it stopped:
olpc-update 767
4. At the end of the upgrade, you will see "Installing update in...." or "Update Succeeded!" You are halfway done. At this point, type reboot reboot your machine. You can do this by typing reboot from the terminal.
5. Connect to the Internet again. As soon as you reboot, you will see a bar at the top of the screen that says "Software Update" with options "Cancel" / "Later" / "Check now". Be sure you are online before choosing Check now; you can leave the home view to do so.
6. Download and update your activities.
- In case you don't see the option from your Home view, you can still launch it from the Control Panel's Software Update feature.
- First the XO will check online for any updates, then it will ask if you want to install them. Click "Install selected" to update all to the newest versions. By default, the activities checked are those included on G1G1 2008 builds.
7. Add new Collections and Activities.
- After you upgrade your current activities, while still in the Software Update screen:
- a) click on the triangle next to "Modify activity groups" at the bottom of the screen
- b) for the Group URL, enter
http://wiki.laptop.org/go/Activities/Allor some other page that lists activities on the wiki, and select the Add button - c) click on the Refresh button, and wait for the activity list to refresh, then choose "Install selected" to download them.
These changes should take effect without a reboot.
Congratulations, you've upgraded!
If your XO is not online
This process should take 10 minutes once you have downloaded the files onto a USB key.
You can use another computer that is connected to the internet (a desktop at home, a computer lab, etc.) and a USB storage device to upgrade your XO. This process will COMPLETELY erase ALL files on your XO. Make sure you have backed up any files you want to save.
1. Backup any files or journal entries you want to keep.
2. Download the following files to an otherwise empty USB storage device attached to your non-XO computer (do not open the files):
- http://download.laptop.org/xo-1/custom/g1g1/gg-767-4/gg-767-4.img 450 MB
- http://download.laptop.org/xo-1/custom/g1g1/gg-767-4/fs.zip 297 KB
3. Turn off your XO and connect your USB storage device to it.
4. Hold down all four gamepad keys (on the right side of the screen, above the power button). While still holding the four gamepad keys, push the power button to turn the XO on. Keep holding down the four gamepad keys until the message "Release the game key to continue" appears on the screen.
5. Release the gamepad keys. You should soon see a grid of black boxes on your screen, which begin to fill with color. Your XO is now reflashing. It will take about 10 minutes and your XO will automatically reboot when it is done. Once your XO reboots, you should be ready to go.
