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.

Background on upgrading

For background information and other options see Clean-install procedure and olpc-update.

If you run into trouble, the Support FAQ and Support team can provide live help.

Build 767 is the last stable build for version 8.2.

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. Turn on your XO.

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.

2. Connect to the Internet.

3. Launch the Terminal activity and type:

su - 
olpc-update 767 

This updates your system to Build 767 and takes 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. Reboot after you see the "Update Succeeded!" message.

At the end of the upgrade, you will see "Installing update in...." and "Update Succeeded!"; you are halfway done. Type 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"... and you will not have most of your old activities available from your Home view. Get online before choosing Check now.

6. Download and update activities.

Choose Check now from the options at the top of your Home view. If you don't see these option, you can launch it from the Control Panel's Software Update feature. The Control Panel is an option on the hover menu at the center of your Home view.

Your XO will check online for new activities and updates. Click "Install selected" once it is done to update everything. By default, the activities checked are any already on your machine and those included on G1G1 2008 builds.

7. Add more 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/All or some other subpage of the Activities page, and choose the Add button

c) choose the Refresh button, wait for the activity list to refresh, and Install selected to download them.

These changes should take effect without a reboot.

Congratulations, you've upgraded!

Upgrading offline

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.
