Sugar on a Raspberry pi is functional, stable, and ~~testable~~ unsupervised by children ~~(in progress)~~.

+

Sugar via Sweets is possible on a Raspberry pi. It is functional and stable, and tested unsupervised by children. The install process is time consuming and individual Activities can take anything from 15 to 75 seconds to start, so some patience is required.

−

~~== Method ==~~

+

This method has been tested on the following four images:

−

~~Using a Raspberry pi, running OS~~ from http://www.raspbian.org/ ~~(pisces image) on~~ a SanDisk 4 GB, class 4, SDHC card.

+

from http://www.raspbian.org/

−

~~The Raspian install should be fully updated as per their pages. Take care to obtain the most accurate possible configuration of locales~~, ~~keyboard and sound~~.

+

:rpi_pisces_r2.img ''and'' rpi_pisces_r3.img

+

and from http://www.raspberrypi.org/downloads

+

:2012-07-15-wheezy-raspbian.img ''and'' 2012-09-18-wheezy-raspbian.img

+

using a SanDisk 4 GB, class 4, SDHC card (generally successful) and a PNY 8 GB, class 4 SDHC card (with more errors).

The Sugar via Sweets installation process instructions are here:

Line 9: Line 14:

[[Platform Team/Guide/Sugar via Sweets]]

−

and ~~the method follows the walkthrough here~~:

+

The Rasp pi install is updated and upgraded.

+

First install gnome-packagekit:

+

sudo apt-get install gnome-packagekit

−

~~[[Testing/Reports/~~Sweets ~~on Debian Wheezy]]~~

+

Now as a "helper" to the Sweets installer add these python packages

−

~~Refer to [[#Still to Fix]] and attempt to~~ install ~~those items straight after:~~

+

sudo apt-get install python-vte python-gst0.10 python-pygame python-webkit python-beautifulsoup

−

~~sudo apt-get install gnome-packagekit~~

+

[[#Soft reboot|Soft reboot]] the Rasp pi before proceeding.

−

~~'''Test report Sugar 0.94'''~~

+

Download the installer,

−

~~All Function keys, F1 to 6, work fine~~

+

wget http://download.sugarlabs.org/sweets/sweets/installer.sh

−

~~All Views and avatars seen correctly, without error~~.

+

−

~~Software Updates fully functional~~.

+

then run the installer:

−

~~The list of working Activities (and limitations) is very similar to those reported~~

−

~~here [[Testing/Reports/Sweets on Debian Wheezy]]~~

+

sh installer.sh

−

~~''' GUI Activity install '''~~

+

Logout of LXDE, then {{Code|startx}} or [[#Soft reboot|Soft reboot]] the Rasp pi before proceeding.

−

~~This method is useful if a working browser is not available in Sugar. We~~ can ~~use~~ the ~~host browser, Midori, and pcmanfm unzip tool~~.

+

You can view the sweets help file with this command.

−

~~Select a new Activity from ASLO, http://activities.sugarlabs.org//en~~-US/sugar/ . (Packages selected to run in Sugar 0.94.1 can be identified in ASLO, using "Advanced Search"). Using Midori, download chosen Activities to, say, ~/downloads. Open ~/downloads with pcmanfm, select the NewActivity.xo, right click, chose extract to, enter ~/Activities, press Save. The Activity will unzip ready to use. You can check in ~/Activities that you have NewActivity.activity

+

sweets -h

+

Seeing the help page confirms that the installer has run correctly.

+

In recent tests with 2012-09-18-wheezy-raspbian.img, this error response was seen:

+

bash: sweets: command not found

−

~~==== Still to Fix ====~~

+

Running {{Code|echo $PATH}} reveals:

−

~~The current Sweets installer does not pick up all of the dependencies first time in Debian and Raspbian.~~

+

echo $PATH

+

/usr/lib/arm-linux-gnueabihf/libfm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games

−

~~The dependencies that will require manual installation are listed in~~ the ~~steps below~~.

+

To fix this, add this line to the foot of ~/.bachrc

+

export PATH=$PATH:/home/pi/.local/bin

−

~~They are listed in order~~ of ~~ease. The latter items are probably more fundamental to~~ the ~~process. ''The best fix is still required~~.''

+

Logout of LXDE, {{Code|startx}}, then {{Code|sweets -h}} displays the help page correctly.

+

−

~~sudo apt-get install python-vte python-gst0~~.~~10 python-pygame python-webkit~~

+

'''Launch first sweet.''' (Launches a fairly recent version, marked "testing").

−

~~sudo apt-get install oss-compat python-gst0~~.~~10-dev python-gst0.10-dbg timidity~~

~~The following assets may also be required, but~~ not ~~yet fully resolved~~.

We now have Sugar in a window

−

''- is ~~xulrunner fundamental~~ to the ~~task?''~~

+

Function keys, F1 to F6, all views and all avatars work correctly.

−

+

−

~~These are~~ the ~~remaining problem dependencies for -S option~~.

+

There are no Activities installed and visible in F3 view. Click on central avatar => My Settings => Software updates.

+

Mark to update: Arithmetic, Chat, Implode, IRC, Log, Maze, Memorize, Pippy, Terminal. Then Install updates.

+

The loaded Activities now appear and will start from the F3, List View. They do not appear in the F3, Favorites view, until after a restart.

+

The author recomends updating a maximium of ten activities at one time. Use those Activities a little, and soft reboot before updating more Activities.

+

=== Soft reboot.===

+

During testing I had unexplainable errors - possibly related Rasp pi not being able to write to certain SD cards fast enough.

+

When a reboot is needed, rather than just {{Code|sudo reboot}} from within LXDE, perhaps, enter command {{Code|top}} and watch while CPU activity subsides, then logout of LXDE and shutdown from console. And/or, from the console, {{Code|top && shutdown -r now}}. Further, after the downloads and other sections of prolonged 100% CPU activity, I have tended to use the Rpi for some light work with the idea of "settling the contents", and have an extra restart.

+

=== GUI Activity install ===

+

This method is useful where a working browser is not available in Sugar. We can use the host browser, Midori, and pcmanfm unzip tool.

−

2. ~~error status "dr" sdk~~/~~pyabiword~~ (0.8.~~0-11~~).

+

Select a new Activity from ASLO, http://activities.sugarlabs.org//en-US/sugar/ . (Packages selected to run in Sugar 0.94.1 can be identified in ASLO, using "Advanced Search"). Using Midori, download chosen Activities to, say, ~/downloads. Open ~/downloads with pcmanfm, select the NewActivity.xo, right click, chose extract to, enter ~/Activities, press Save. The Activity will unzip ready to use. You can check in ~/Activities that you have NewActivity.activity

−

~~Aptitude shows python-abiword 0~~.~~8.0-11 installed~~.

+

Alternatively you could take the SD card to a PC and transfer or download a collection of Activity.xo files onto a folder on the SD card, then unzip them on Rasp pi as above.

−

~~3. error status "dr" sdk/hulahop (0.8.2-7)~~

+

=== Activities ===

−

~~E: Package~~ '~~python-hulahop~~' ~~has no installation candidate~~

+

'''Working'''

−

~~Package: python-hulahop (0.8.1-1) is shown in Debian package search as unavailable in armhf~~

+

'''Working with difficulties'''

−

4. ~~error status "dr" sdk/pyxpcom (1~~.9.~~2-15) (<2)~~

+

Chat, ok, but fails to install at first attempts.

+

Physics, seems to be running at 100% CPU at rest. However it can be demonstrated running.

+

'''Not working'''

−

~~Package: python-xpcom (1:9.0~hg20111212-2 and others)~~

+

Browse Paint Read Record Ruler Speak TamTamMini Write

−

~~Aptitude shows python~~-~~xpcom 1:9~~.0~~~hg20111212 ''~~but ~~it is out of specified range~~.''

+

As an alternative to Browse, you could experiment with Surf available from: http://people.sugarlabs.org/Tgillard/Surf-115.xo . Surf works in version 0.88 but fails in version 0.94.

−

~~https://developer.mozilla~~.~~org/en/Building_PyXPCOM~~ '~~'refers~~''

+

=== Extra mile ===

+

'''Further dependencies.''' It is a known issue in Debian, that the "suggested dependencies", that is, -S sweets command argument, generally fails.

−

~~5. error status "er" http~~:~~//sweets.sugarlabs.org/sdk/xulrunner~~ (~~>=1.9.2, <1.9.3~~)

+

Here is a workaround: in order to get the maximum number of Activities to run, install (or check that you already have the newest version) by running this command:

−

~~Package, squeeze: xulrunner~~-~~1.9.1 (1.9.1.16~~-~~16) [security]~~

+

sudo apt-get install python-xlib python-gnome2 python-lxml python-csound python-elements evince

−

~~Package~~, ~~sid~~: ~~xulrunner-1.9.1 (1~~.9.~~1.19-2 and others)~~

+

But,

+

$ sweets -S dextrose/sugar:emulator = 0.94

+

still fails to open a window.

−

~~Package, wheezy, xulrunner-10.0 ''Is available, armhf: testing in progress''.~~

+

=== Review ===

−

~~''All are out~~ of ~~specified range~~.''

+

The above method has fulfilled all the "install" dependencies of the four <sweets> versions, sdk: 0.88, 0.94, and dextrose: 0.88, 0.94, so far as is revealed by:

−

~~https://developer.mozilla.org/en/XULRunner_1.9.2_Release_Notes ''Refers, attempted and failed to install, (i686 source)''~~

+

sweets status --deps <those four sweets>

+

and (having run the [[#Extra mile|Extra mile]] list)

+

sweets status --deps -S <those four sweets>

+

'''Remaining errors.''' This error message keeps appearing:

+

ls: cannot access /usr/lib*/xulrunner-1.*: No such file or directory

+

Remaining unresolved dependencies for {{Code|-S}} option. This is edited output list after cutting all "ok" items.

−

~~'''As a known issue'''~~ (~~for Debian~~), ~~suggested dependencies, i~~.e., -S sweets ~~command argument~~, ~~don't work for now~~. ~~The reason why the~~ -~~S option does not work in Debian is probably fundamental to making the above process more easy to complete~~.
