Updating Sugar
from: http://en.flossmanuals.net/Sugar/Updating
You might want to periodically update the Sugar learning platform or your favorite Sugar Activities when new versions are released. The Sugar community actively evolves and improves the Sugar platform. New development releases are available on a daily basis. Stable releases are made every six months. Sugar Activities are also being improved.
The Sugar learning platform is most often updated as part of an operating-system upgrade; for example, in upgrading Ubuntu from Version 8.04 to 8.10, the Sugar release updates from Version 0.71 to Version 0.82. Typically, Sugar Activities are updated separately.
You can keep your Sugar Activities up to date in four ways:
When you have an Internet connection, updating through the Sugar Control Panel is the easiest way to keep your Activities up to date.
You can update individual Activities by installing the latest versions through the web browser.
You can update an Activity .xo file from removable media by copying it to your Journal.
If you are comfortable using the Terminal Activity, you can use Linux commands to install and update Activities.
On Fedora-based systems, use the "yum" command.
On Debian-based systems (including Ubuntu), use the "apt-get" command.
You can update Sugar and the underlying operating system without losing any data. You can update Sugar one of these three ways:
Refer to wiki.sugarlabs.org for the most recent version number and for information about updates and reasons for updating.
To determine what version of Sugar you are currently running, hover the pointer over the XO icon on the Home View and go to Control Panel, and then click About my XO.
su -land then press enter.
olpc-update build-numberand then press enter. (You should replace the string "build-number" with the number of the build you would like to upgrade to, for example, 8.2-757.) Alternatively, you can use the --latest flag to get the latest build, for example,
olpc-update --latest stable
Before you begin, you need to download two files to a USB stick. You can find the osNNN.usb and osNNN.toc files at http://download.laptop.org/xo-1/os/official/, where NNN is the version number you want to install.
su -land then press enter.
olpc-update --usband then press enter.
Reboot your computer.
Follow the standard process for updating Ubuntu to the latest release. The new Sugar packages should be included as part of the upgrade.
You can update the system files without updating the underlying operating system.
su -land then press enter.
yum -y updateand then press enter.
yum install sugarand then press enter.
su -land then press enter.
apt-get -y updateand then press enter.
apt-get install sugarand then press enter.
