Stuck at 6.06LTS and no flashplayer.

[hermanaa]

I cannot upgrade beyond Ubuntu 6.06LTS. I can live with 6.06LTS for now.
 (I bring the upgrade-problem to the list later).

However 6.06LTS has no flashplayer.
 Yesterday I had to go to Windows to see
 http://buyqube.com/ (the website relies heavily on flashplayer).

Soooo .... I am terribly STUCK! (no flashplayer and no upgrade
possible).
I put off buying a new computer till I have a handle on my problems.

My present OS: 6.06LTS.
Processor: x86 Family 15 Model 6 Stepping 5 GenuineIntel ~2793 Mhz (x2,
dual CPU)
Processor: Intel(R) Pentium(R) D CPU 2.80GHz (2 CPUs)
BIOS Version/Date	Phoenix Technologies, LTD 6.00 PG, 1/19/2008
Motherboard: Foxconn 945GZ
 
The problem: I cannot get flashplayer working.
Flashplayer was working the last 2 years (same OS, same computer).
I recently re-installed 6.06LTS. The system got updated OK (239
downloaded updates, afair).

My FireFox is version 1.5.0.12eol (default, incl. upgrades, 6.06LTS
installation).
 Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.0.14eol) Gecko/20081113
Ubuntu/dapper-security Firefox/1.5.0.12eol
My system is kept up-to-date by regular updating via Internet, by
Ubuntu.

IN SEQUENCE OF the EVENTS:

##Synaptic says that Flashplayer is installed:
 --flashplugin-nonfree
 Adobe Flash Player plugin installer--
.... but does not work when FireFox displays a website.

##I uninstalled the installed 'flashplugin-nonfree'
 (using Synaptic) 'remove completely'

##I installed (I first closed my FireFox browser)
 (using Synaptic, Mark, Apply)
flashplugin-nonfree (version 9.0.48.0.0ubuntu11~dapper3) will be
installed
  [this loos same package as: --flashplugin-nonfree
   Adobe Flash Player plugin installer--]
It now shows 'installed' in Synaptic.
Testing is next: I start up FireFox, check a website:
 Flashplayer not working. I restart my OS/computer.
 FlashPlayer not working. I cannot read/see http://buyqube.com/

###End of this exercise.

I tried previously: 'Install plug-in' as it appears on the webpage: 
 Adobe Flash Player plugin version 10
 'This package officially supports the following browsers:
  Firefox 2.x, Firefox 3.x, SeaMonkey 1.11 '
 (note that my installed FireFox version is not included).
IT DOES NOT INSTALL. (Adobe version 10). It gives:
 Error: conflict with the installed package 'xfs'.

With no Flashplayer, and no alternatives, I am just about stuck !
