Install GNOME 2.28 (and network-manager) on Knoppix 5.3.1DVD

Hello. I installed KNOPPIX 5.3.1 DVD on HDD.
Now I want to install network-manager (gnome) but i can't!
I tryed with apt-get, with synaptic, with kpackage, it does not work. I also tryed to install the dependencies, manually, one by one..
It always sems to stop at python or some packages from python. I tryed to remove them manually (because the package was always stopping at their removal), but i encountered other problems. I tryed to upgrade python, remove python packages (doh!), tryed to remove some x-window-managers, and session managers, nothing seems to work. Because all the problems, I had to install it on WMvare, and I made a copy of the knoppix newly installed then I replace it after I get an error. I'm doing that for a while, i think i copied the image files in WMvare for at least 50 times.
Please, if someone can help me, please do!
#edit: I also tryed with the hint to use only unstable sources. Tryed to install gnome, again, same result!

I managed to install GNOME on knoppix DVD 5.3.1 installed on HD
Unfortunately It needs a newer kernel. Still, it works, but udev gives one error, but it works.
I have written how i did for the newbies like me... This is now, maybe it will change, but you have one start...
I assume that you already have internet connection :) and all comands must be run as root :D
The libxklavier12_3.9-1_i386.deb and libgnomekbd3_2.26.0-1_i386.deb will be downloaded from debian squeeze (testing) because are missing (for now) in unstable i386
------

Code:

---

vi /etc/apt/sources.list

---

and comment all lines except unstable ones

Code:

---

vi /etc/init.d/knoppix-autoconfig

---

and modify default desktop-in gnome (from kde)
with kuser make knoppix user member of netdev (or use command line) (to be able to use network-manager)
reboot
You have gnome now, but not 2.28
Then i removed the packages that stopped the installation in my previously attempts (with an error) when dpkg tryed to remove them.

Code:

---

apt-get remove python-wxgtk2.* python-vtk python-wxversion pioneers*  libqt4-dev libquantlib-0.8.1 emacs* konqueror*

---

Update

Code:

---

apt-get update

---

Then I installed some packages that also stopped the installation with an error on my previous attempts when dpkg tryed to install them.

Code:

---

apt-get install libcucul0 libsasl2-2 libauthen-sasl-perl libjack-dev libquantlib-0.9.7 bogofilter

---

Then i started to install gnome and his dependencies

Code:

---

apt-get install dpkg
apt-get install libgnomekbd-common
apt-get install libgtk2.0-0

---

Now download and install the missing "testing" packages from squeeze.

Code:

---

cd /home/knoppix/Desktop/
wget http://ftp.at.debian.org/debian/pool...3.9-1_i386.deb
wget http://ftp.at.debian.org/debian/pool...6.0-1_i386.deb
dpkg -i libxklavier12_3.9-1_i386.deb
dpkg -i libgnomekbd3_2.26.0-1_i386.deb

---

Install the rest...

Code:

---

apt-get install gnome-screensaver
apt-get install xorg
apt-get install xserver-xorg-video-all
apt-get install gnome

---

Change default windowmanager and sesionmanager

Code:

---

update-alternatives --config x-window-manager

---

and choose metacity

Code:

---

update-alternatives --config x-session-manager

---

and choose gnome-session (auto)
Then I made some modification because some programs not worked (network-manager)

Code:

---

sudo gtk-update-icon-cache -f /usr/share/icons/hicolor

---

Then make network-manager able to manage your connections

Code:

---

vi /etc/NetworkManager/nm-system-settings.conf

---

and change

Code:

---

[ifupdown]
managed=true

---

(optional)
Restart it with

Code:

---

sudo killall nm-system-settings

---

Reboot
Now it supposed to work :)
