Please count me also on the list of who wasted a lot of time installing python 2.5, I post these few lines here since they maybe clarify a bit, it seems the python-bluez 2.5 package is broken and requires libbluetooth1 that was on mistral while on bora is libbluetooth2.

So, in order to install 2.5 on bora, you need to add mistral repository, this is why removing trailing extra, i.e. enabling normal mistral repository, solved the problem.

See the line that starts with 500 below

/ # apt-cache policy libbluetooth1
