Well, i have tested the installation with the .install-file on my N800, which was reflashed recently, the only additional repository i had in my application manager was that i enabled the extras-repository.

In this case the installation worked without any problems.

I am very certain that the problem you are seeing may be caused with some kind of conflict between some packages, probably from other repositories. You could try to call "apt-get -f install" and see what apt-get wants to do.

At least the message "dpkg-deb (subprocess): error in buffer_read(stream): failed to write to pipe in copy: Input/output error" does not sound very nice - are you shure that you have enough space left for the packages?

I am also interested in the output of the following 2 commands:

apt-get install libgoffice-0-6
apt-get install libgsf-1-common
