How to Install New Official XO-1 Signed Sugar Build os850

   
   
   
   
   

After almost 2 years OLPC released the first officially signed new build for the XO-1 (and XO-1.5), os850. So if you are still running official OLPC builds (os656/os802) and never bothered with developers keys etc, here is a build that will breathe new life into your XO-1.

The build is Fedora-11 based and comes with dual boot, Sugar and Gnome, eg is a "Best OS image ever" class build. However in this case installation is much simpler:

How to install signed build os850 of release 10.1.2 on XO-1

The build is installed to the internal NAND flash device. You will need a USB memory stick of at least 1Gb capacity, but only for the duration of the installation.
ALL USER DATA WILL BE ERASED FROM THE LAPTOP!

olpc sugar

Prepare the USB memory stick:

  1. Download os850.img,
  2. Save the file to the top directory of a USB memory stick,
  3. Download os850.img.fs.zip,
  4. Save the file to the top directory of a USB memory stick,
  5. Rename the file to fs.zip, <--- key step!
  6. Check the USB memory stick contains at least the two files fs.zip and os850.img.

Prepare the laptop:

  1. Make a copy of any data you wish to keep,
  2. Ensure the battery is in the laptop,
  3. Connect the laptop to external power,
  4. Turn off the laptop, unless it is already off.
  5. Insert the USB memory stick into any USB port on the laptop,

Start installing:

  1. Hold down all four game keys (see this in pictures),
  2. Turn on the laptop,
  3. Wait for the message Release the game keys to continue,
  4. 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. Remove the USB memory stick during or after the reboot. The USB memory stick can be used on other laptops.

You can even upgrade to this build if you are running os767/os802. There are some caveats in upgrading but nothing unusual, and you get to keep all your data too or even go back to your old build!

This is a "release candidate" build which means one or more additional ones will come before the "final", depending on YOUR testing. The build is very solid but the more people use it the more likely bugs will be identified and hopefully squashed out before the final.
So please install, test and report.

Hola!

I got the new version, but went back to my old os656 version after I was not able to add Yum install "files" using Terminal.

I'm afraid yum will/can not be fixed for anything bigger than 5-10 MB http://dev.laptop.org/ticket/10285 :-(

You can use some swap or go to even more drastic changes ( http://www.olpcnews.com/forum/index.php?topic=4867.msg32364#msg32364 ) if really big and complex packages are to be installed.

With all of the dependencies needed when adding new activities, can't another activity be run that can handle the Swap, Umount the tmpfs, and stop Sugar before attempting Yum?

Couldn't Yum just be added for the OLPC side and then later the Fedora side? It would need less memory.

Thanks for the link about the Yum issue is not planning to be corrected.

In the first upgrade for G1G1 XO-1 systems, there were lots of warnings about needing to install activities on the USB stick as well, since the system itself didn't include any, and without a browser or terminal, it would be hard to add them. I never upgraded back then, but am thinking of doing so now. Do the same caveats about having to bundle the activities on the USB stick apply to this new update, and if so, are there new directions for doing so?

I saw no problems, except for the Yum install issue and maybe that the new install uses more of your free space adding Sugar/Gnome.

You can go back to your old version, if you do not like it as done by me.

Installed Monday on all but two G1G1 systems. Three mesh channels show up. Friends (button two) generally empty. Speak activity does not seem to provide Share with Neighborhood capability. On Settings, there is check-box which says Turn off radio to save power (Network) but when I CLEAR the check-box, it turns the radio OFF when I put the CHECK mark back, it turns the radio ON, opposite of what I would expect.
As a result of all this, have not yet figured out how to share such as Chat and so forth. These are used in after-school tutoring once a week public school students

I'm assuming that you are using os852 and you have been through the release notes
http://wiki.laptop.org/go/Release_notes/10.1.2 ...

Should not be any problem with collaboration.
Are the XOs connected to an access point? or ad-hock sharing? Are there any XO-1.5s in the mix?

No access point, just ad hoc.
No 1.5 system(s) either.
I found: Under the tree is not automatic when mixing laptop models
In the absence of a wireless access point, a group of mixed XO-1 and XO-1.5 laptops will not automatically begin to collaborate over wireless. A workaround is to create a new wireless network from one of the laptops (frame key, right-click on wireless icon), and then join it from the other laptops. Development is continuing toward a fix, and it is nearly solved
