You are still giving me more credit than I deserve to solving problems like you are experiencing

I was hoping to actually see the 'messages' produced by your attempt to install 'python2.5-gpsbt' from the command line.

In any case, three things that I notice about your repository listing that *might* cause trouble (hey, I am just a user like you!) are:

1) You have the 'repository.maemo.org/extras' for *both* chinook and diablo -- maybe try temporarily getting rid of the diablo one (I don't have that one)
2) You have those repositories mentioned *twice* (two for chinook, and two for diablo) -- I think this might be asking for trouble
3) You have the 'repository.maemo.org/extra-devel' for diablo, but I do not (this might be OK)

I am personally running out of ideas to help -- like I said earlier, you may want to post your question to a different thread, since this is not directly related to Mephemeris -- simply to your (legitimate) desire to install 'python2.5-gpsbt' on your tablet.
