Reproducible builds of Debian as a whole is still not a reality, though individual reproducible builds of packages are possible and being done. So while we are making very good progress, it is a stretch to say that Debian is reproducible.

Big outstanding issues

These are the critical items necessary to have reproducible builds for at least the required packages of Debian

Annoying but not major

Nice to have

Also related

There are many other possible nice-to-haves, e.g., making builds independent of their build directory, making it possible to create archive formats (like tar.gz and zip) with different tools yet result in the same byte order, etc. Many of those are valuable, but they shouldn't distract from getting the results of reproducible builds out to users.

Even more

For more concrete tasks to be done, look at how to contribute.
