Why is not possible to install other languages for LibreOffice???????????????????

I don't have an answer to your question, but if some of our senior
members don't have an answer either, then I have an alternative you might consider.

PCLinuxOS has an LXDE version similar to Knoppix, but an older kernel, and not
as good on some video drivers as Knoppix. Has a peculiar way of handling LO.
It is not in the base install, but an option loaded with 'LOManager'. IIRC,
LOManager has an option up front to select the language, and is not limited to just
English & German. Perhaps that's why it is handled this way.

Hope that helps.
