Mailman 2 will never support python 3 and it has been removed from unstable and testing (see mailman3 for the future, but bear in mind it's very much not a transparent upgrade). That said, as far as I can tell even in unstable, /usr/bin/python is still pointing to /usr/bin/python2.7, so you must have manually changed the link in /usr/bin/python behind the packaging system's back? It does appear to be a bug in this package that /usr/bin/python is used (Python policy says that /usr/bin/python2 must be used if the application requires a specific major version of python), but in practical terms it doesn't appear need fixing since the default isn't going to change in the stable releases. I've attached a trivial patch for completeness (which I prepared before I realised that there is no supported mechanism to actually switch /usr/bin/python that I can see) in case it's of help. If you're manually changing files in /usr/bin, you could of course just fix the scripts to specify /usr/bin/python2 by hand, though I don't recommend this approach. Dominic
