installing on system already running ubuntu 9.04

Hi all!!
I would like to install complete CAElinux on a system already running Ubuntu 9.04
I have32 bit on my desktop and 64bit on my notebook.
I have tested live CD on my notebook and works fine.
but now I want to install into my existing system without messing it.
What would be the best procedure to do this?.
Many thanks in advance!!!
best regards

I think that you can't.

Two main problems:

1) Ubuntu 9.04 comes with python 2.6 and it is clarified that Aster 9.4 works only with python 2.4 or 2.5.

2) Caelinux is an entire operating system, not just a suite of application, so if you try to install it over ubuntu 9.04, it will overwrite the whole operating systm.

Try one of these following options:

1) If 32 bits are enough for you, donwload and istall Salome-Meca 2009 (you have to check if the python-release difference is a &quot;stopping&quot; issue or not).

2) Install Caelinux on a different partition. you will have to reboot to switch form one to another.

I have had the Salmome-Meca 32-Bit package working under 32-Bit Ubuntu 9.04.

There are 3 or 4 libraries you need to install with apt/synaptic. Those hidden dependencies will be listed as errors, in a log file in a folder in your home directory, the name of which which escapes me right now. As Alessandro said, one of those dependencies might be the older python.

I found that I could install Salome Meca in its own folder under /user/share/, and it will run from there, normally.

I found that when making a launcher with Gnome, you must select the &quot;Run from Terminal&quot; option.

I've tried the 64bit version of CAELinux, and it's a nice suite, but I still would have preferred 9.04 than 8.04 LTS. For instance, 8.04 won't let me unlock and change the processor speed, and the nVidia drivers, don't work quite the same when choosing multiple monitors as those from 9.04 do. Come to think of it, multiple monitors was broken under 8.xx, for most people. I guess they fixed it somewhat.

I have yet to try CAELinux yet (burning ISo now..) so this may be innacurate - buti do have a limited amount of linux experience from previous years and i know that i have upgraded OS from Ubuntu 7.xx to 8.xx (or maybe it was 6.xx... ?) natively from its standard update module and had not lost any installed programs or files. and I can't imagine any compatibilty issues as that isn't a typical linux occurance. so i suppose your solution is to simply upgrade. however, in most cases that &quot;features&quot; provided in any disto are simply 3rd party modules that have been included with the base install as a feature - you should be able to install these applications regardless of your current version (again, in most cases...)

as for installing these programs on your current linux install - isn't what is being offered here simply a collection of softs? unless i'm incorrect in that statement I would jsimply install everything being listed as included with the ISO here... can't imagine that there would be a difference unless the creators of the ISO decided to offer some certain modules thru their ISO only - something that I really can't imagine happening.

happy hunting

okay, so now I've tried it...

I had video issues in live boot, and I'm not about to partition my companies workstation.... so my only option was to use the main Ubuntu distro install that creates a file in windows to behave like the Linux disk (no partition needed)

so now I'm trying to find the various packages to install and having a hard time with some...

I suppose the only suggestion i can make is to the CAE devs - add the option to create full install without creating a new partition (this option can be found by loading the Ubuntu CD in the windows environment)
