package texlive-base-bin 2007.dfsg.2-3ubuntu1 failed to install/upgrade: subprocess pre-installation script returned error exit status 1

I am currently using Ubuntu 8.10. I have certain upgrade problems due to version locked TexLive Packages

1) I am not updraging any of the TexLive packages from Ubuntu Repositories ,
    since I want to keep using my current installation

2) For this prupose I have explicitly locked TeXLive related packes by installation commands like

aptitude install texlive-common=

3) Also TexLive related packages are locked in Synaptic.

4) But "Update Manager" keeps showing me this packages as Upgradable on my desktop panel all the time.

5) Last night when I wanted to install some of the security updates for Firefox 3.0. I had deseclected all the Texlive packages which Update manager keeps showing, but even than it tried to acces those version locked packages and showed me error message. Hence cancelled the update.

I hope Ubuntu team will be able to find the problem. Thank you.

More importantly I had cancelled Jaunty 9.04 OS Upgrade , because of ATI card proprietry driver fglrx not
present. I need to wait some time, the last free driver was giving me some strange flickering on top of screen
before showing logging screen for Ubuntu, once I installed proprietry driver problem was solved.

I hope there was not conflict with cancelled Jaunty (9.04) installation.
