Hi szzsqing1

Yes I got the same message when replacing Libreoffice with Openoffice, see my post:

http://www.knoppix.net/forum/threads...reOffice-3.3.3

I got rid of the error message, [which would come up again each time I tried to install any other software using synaptic or aptitude] by simply uninstalling postgresql8.4 and postgresql-common [and maybe a couple of other related installed packeges that came up in a synaptic search for postresql packages].

This seems to leave Openoffice [and all the other programmes that I use] still perfectly functional - but of course it might mess up something else you needed to run [but which i don't use]. So far it hasn't bothered me.

So that is a possible fix but definitely not an elegant one. I wonder if it is due to there being later versions of postgresql in the synaptic package list, v9.0 and v9.1 and perhaps the new Libreoffice prefers to work with one of them rather than with v8.4 [the installed version with knoppix 6.7.1] - but this is only a guess.

Best wishes, John
