I use a software (Anki) which is in version 0.9.9.8.6-2.1 in the Debian repository and in version 1.2.11-1 in the Ubuntu repository. Quite a lot has changed meanwhile (changelog). The latest version is 2.0.8. Source code and a Debian package is already available (see downloads), but it is not in the repository.
Question 1: Where or who can I ask to update this package?
Question 2: When it gets updated in the Debian repository, will it automatically get updated in the Ubuntu repository?
