skatebiker: 1) Just so that we are comparing apples-to-apples, provide the repository listing the same way that I did -- what I did (in a terminal) was this command: cat /etc/apt/sources.list.d/hildon-application-manager.list I notice from the Gronmayer repository searcher (http://www.gronmayer.com/it/index.php) that 'python2.5-gpsbt' is in *both* the 'chinook' and 'diablo' repositories, and that (I think) that I only have the 'chinook' one enabled, even though I am running 'diablo'. 2) I am confused -- if you don't have 'python2.5-gpsbt' installed, then there should be no risk of disrupting any applications if you attempt to remove it (in fact you don't even need to try if that is true), so why not go ahead and try the 'install' that I suggested. Are you worried that might disrupt as well? Sorry, I don't know how to 'backup' in case that occurs, but it seems unlikely to me!
