Installing sugar on Debian Unstable

For now Sugar can only be installed on a mix of unstable (SID) and experimental.

Prerequisites

Python 2.5 is installable from Debian testing but, as of 2007 Feb 16, it is "unsupported" in the sense that python modules are not compiled with support for 2.5 by default.

To cause Python 2.5 be supported, you can edit /usr/share/python/debian_defaults.

[DEFAULT]
# the default python version
default-version = python2.4
# all supported python versions
supported-versions = python2.4, python2.5
# formerly supported python versions
old-versions = python2.3
# unsupported versions, including older versions
unsupported-versions = python2.3

Shown above is a copy of my debian_defaults. Yours might look a little different. The important thing is to check where python2.5 is listed.

You may need to change the default python in your $PATH as well:

cd /usr/bin
sudo ln -sf python2.5 python

Recompiling

Before beginning, install tools indicated in debian maint-guide. Also, you need to make sure the experimental source archive is listed in /etc/apt/sources.list:

deb-src http://ftp.debian.org/debian experimental main  #important!

# Also may be required:
deb http://ftp.debian.org/debian testing main contrib non-free
deb http://ftp.debian.org/debian unstable main
deb http://ftp.debian.org/debian experimental main

Now that Python 2.5 is "supported" on your Debian box, you need to recompile any python packages which are required by sugar. An easy way to do this is to use apt-src. For example:

$ mkdir debian   # keep your work somewhere temporary
$ cd debian
$ apt-src install python-dbus

Here is a list (maybe incomplete) of python packages you will need to recompile:

• python-avahi
• python-cairo
• python-dbus
• python-gnome2-desktop
• python-gobject
• python-gtk2

If you neglect to recompile a python package which is indeed required by sugar then hopefully you will get a helpful failure message indicating where you are remiss.

suger-jhbuild

If you had already checked out sugar-jhbuild previously, make sure your copy is up-to-date before building:

cd sugar-jhbuild
./sugar-jhbuild update

• Read the instructions Sugar_with_sugar-jhbuild, and also check Sugar
• ./sugar-jhbuild build-base. If the dependency check fails, then try installing the following packages. I'm no expert on what's really required, but it worked for me. (I use debian unstable, march 2007).

This list was compiled before the sugar crew moved to python2.5, so it is possible that installing some of these python things does more harm than good (they will be 2.4 versions I believe... see note above on recompiling for 2.5.) On the other hand, maybe the ./sugar-jhbuild build-base makes custom versions of the required python modules, and these have absolutely no effect... I don't know.

apt-get install  automake1.7 gtk-doc-tools xnest \
darcs cvs subversion \
libtiff-tools libtiff4 libtiff4-dev libpng12-0 libpng12-dev \ 
gconf2 gconf2-common libgconf2-dev \
dbus python-dbus \
avahi-daemon avahi-utils avahi-discover python-avahi \
network-manager-dev network-manager dhcdbd \
libnm-* network-manager-gnome \
libsqlite3-0 libsqlite3-dev \
libfreetype6 libfreetype6-dev libxml2 libxml2-dev

• ./sugar-jhbuild build
• ./sugar-jhbuild run

Hopefully this command will launch xnest with sugar running inside. Enjoy.
