== Update == |
|||
You may wish to update from a previous version of the operating system. This method preserves most user data, the Sugar Journal and installed Sugar Activities, but does not preserve certain operating system customizations such as additional packages. |
|||
(Update is distinct from install. If you have followed the install procedures above, then you need not follow this section.) |
|||
=== Preparation === |
|||
To prepare for an operating system update: |
|||
* remove as much saved content as you no longer need, |
|||
* remove any large activities you no longer need (in the Home view, erase them), |
|||
* [[Collections#Removing a collection|remove any large collections]] (library content) you no longer need, and; |
|||
* use [[Software update]] to ensure the Terminal activity is the latest available version. |
|||
Follow the instructions in one of the subsections below, according to which method and laptop model you are using. |
|||
=== Simple Online Update === |
|||
See [[Olpc-update#Simple_online_update|Simple Online Update]] for more detail about the method. |
|||
*establish an internet connection from the laptop (if you plan to do online update), |
|||
*start the laptop normally, |
|||
*start the [[Terminal Activity]], and depending on the laptop model type: |
|||
==== XO-4 ==== |
|||
sudo olpc-update 13.2.6_xo4-18 |
|||
==== XO-1.75 ==== |
|||
sudo olpc-update 13.2.6_xo1.75-18 |
|||
==== XO-1.5 ==== |
|||
sudo olpc-update 13.2.6_xo1.5-18 |
|||
==== XO-1 ==== |
|||
sudo olpc-update 13.2.6_xo1-18 |
|||
An online update can be very slow on an XO-1, in one test it took two hours; please consider reinstalling. |

Installation
XO-4
How to install signed build 18 of release 13.2.6 on XO-4.
The build is installed to the internal storage device. You will need a USB drive or Secure Digital card of at least 1 GB capacity, but only for the duration of the installation. We recommend the drive be FAT formatted, but other formats are supported, see how to prepare a drive for use by the firmware for more details.
ALL USER DATA WILL BE ERASED FROM THE LAPTOP!
- Prepare the USB or SD drive:
- Download 32018o4.zd, see How to Download,
- Save the file to the top directory of the drive,
- Download fs4.zip,
- Save the file to the top directory of the same drive,
- Check that the drive contains at least the two files fs4.zip and 32018o4.zd.
- Prepare the laptop:
- Make a copy of any data you wish to keep,
- Check that the battery is inserted and locked,
- Check that the power cord is in place and the battery indicator is green,
- Turn off the laptop, unless it is already off,
- Insert the USB drive into any USB port on the laptop,
- Start installing:
- Hold down all four game keys above the power button,
- Turn on the laptop,
- Wait for the message Release the game keys to continue,
- Release the game keys.
Installation progress will be displayed. Green colour will fill grey blocks. It will take about five minutes. Once finished, the laptop will reboot automatically. You may remove the USB or SD drive during or after the reboot.
The USB or SD drive can be used on other laptops. If installation progress is not displayed, you may be running an old firmware version which does not recognise the fs4.zip file. Please rename fs4.zip to fs.zip and try again. If you see a message Boot failed then either:
- the USB or SD drive has not been properly prepared, or;

- the USB or SD drive has not been properly prepared, or;
- the firmware is out of date and should be updated (see Firmware).
XO-1 with SD card
How to install signed build 18 of release 13.2.6 on XO-1, to an SD card in the external slot.
ALL USER DATA WILL BE ERASED FROM THE CARD!
Ingredients
You will need an SD card of at least 4GB capacity; it will be erased by installing, and should remain in the laptop.
You will need a USB drive of at least 1GB capacity, but only for the duration of the installation. We recommend the drive be FAT formatted, but other formats are supported, see how to prepare a drive for use by the firmware for more details.
You will need an XO-1 laptop. It may be either locked or unlocked.
Recipe
Preparing the USB drive
- download 32018o0.zd (602 MB) and save to the USB drive,
- download 32018o0.zd.zsp.fs0.zip (1 MB) and save to the USB drive with file name fs0.zip,
- check the USB drive has two files; 32018o0.zd and fs0.zip,
Preparing the XO-1
- check the XO-1 has firmware Q2F20, and if not upgrade the firmware,
- shutdown the XO-1,
Installing
- insert the USB drive and the SD card into the XO-1,
- hold down all four game keys above the power button, turn on the XO-1, and wait for the message Release the game keys to continue,
- release the game keys, progress will be displayed, some grey blocks will turn green, and the screen will show:
Blocks/square: 2 Total blocks: 15283 Now writing: 70 0 % Installing to SD card ..... please wait.
- after a few minutes it will show:
Blocks/square: 2 Total blocks: 15283 Now writing: 0 0 % Rebooting in 10 seconds ... please wait.
At this point it is finished. You may remove the USB drive then, during the reboot, or after the reboot.
Warning
Do not remove the SD card.
It is best to leave the SD card in the same XO-1, because;
- the install is a good test of the XO-1, SD card slot, SD card, and compatibility,
- unnecessarily exercising the card slot contacts of very old hardware is likely to cause reliability problems,
- booting from the card and then moving the card to another XO-1 will cause software problems. You may need to Discard wireless connections in the Network panel of My Settings. See also imaging side effects, in particular the sections regarding .olpc-configured, and network.
Testing
Verify the XO-1 has booted from SD card: in the Sugar home view, right-click on the Journal icon, and look at the free disk space. For an 8 GB SD card, the free space is about 5750 MB. Or use Terminal command df and observe the root filesystem is on /dev/disk/mmc/mmc0p2, like so;
[olpc@xo-93-c1-cf ~]$ df / Filesystem 1K-blocks Used Available Use% Mounted on /dev/disk/mmc/mmc0p2 7679632 1772792 5887976 24% / [olpc@xo-93-c1-cf ~]$ █
Try rebooting several times to make sure the SD card is used each time. Unreliable combinations may cause the laptop to boot from internal storage instead.
Update
You may wish to update from a previous version of the operating system. This method preserves most user data, the Sugar Journal and installed Sugar Activities, but does not preserve certain operating system customizations such as additional packages.
(Update is distinct from install. If you have followed the install procedures above, then you need not follow this section.)
Preparation
To prepare for an operating system update:
- remove as much saved content as you no longer need,
- remove any large activities you no longer need (in the Home view, erase them),
- remove any large collections (library content) you no longer need, and;
- use Software update to ensure the Terminal activity is the latest available version.
Follow the instructions in one of the subsections below, according to which method and laptop model you are using.
Simple Online Update
See Simple Online Update for more detail about the method.
- establish an internet connection from the laptop (if you plan to do online update),
- start the laptop normally,
- start the Terminal Activity, and depending on the laptop model type:
XO-4
sudo olpc-update 13.2.6_xo4-18
XO-1.75
sudo olpc-update 13.2.6_xo1.75-18
XO-1.5
sudo olpc-update 13.2.6_xo1.5-18
XO-1
sudo olpc-update 13.2.6_xo1-18
An online update can be very slow on an XO-1, in one test it took two hours; please consider reinstalling.
Simple Offline Update
- Download a .usb and .toc file, see How to Download,
- for XO-4
- for XO-1.75
- for XO-1.5
- for XO-1
- Put them on a USB drive,
- Boot the laptop normally,
- Plug the USB drive into the laptop,
- Start the Terminal Activity, and type:
sudo olpc-update --usb
See Simple Offline Update for more detail about the method.
Known Problems
Welcome Activity
The new version of Sugar does not support the Welcome activity. See <trac>12869</trac>.
Restricted Software
Restricted software, such as browser plugins, codecs, and so forth, are not included in the public release. Deployments who need this software should contact OLPC or make their own builds, see OS_Builder/Add_Restricted.
Also, using olpc-update on a restricted software build will remove restricted software.
Video Playback
The XO-1 cannot play some videos in the Browse or Epiphany web browsers, because the Adobe Flash plugin is no longer available for the Geode processor.
On some models, particularly XO-1 and XO-1.5, although MP4 playback support may be present with restricted software builds, the video to be played may require more processor and graphics bandwidth than the hardware can provide;
- especially true in the presence of advertising or related videos elements on youtube.com,
- also true inside a web browser for Khan Academy,
- not as true when playing the same video in Movie Player or Jukebox,
Workaround is to transcode videos to a lower bandwidth, or to pause playback and wait for advertising to complete.
Frozen Repositories
The frozen repositories have not been updated; the release was made from all Fedora 18 updates.
XO-4 Headphone Detection
XO-4 speakers may remain silent if headphones are removed during automatic power management suspend, or headphones may not work if they are inserted during suspend, <trac>12724</trac>,
Sugar Journal
Journal star does not give immediate feedback, #4904.
Sugar View Source missing scroll bar
View Source is missing a scroll bar, #4903,
