Most of this is correct, except for the part about installing sid from scratch. That's not a thing. If one wants to run unstable, one installs the current stable release, and then upgrades to sid. The probem here is that the OP attempted to mix stable and unstable, cherry-picking packages from unstable. This WILL NOT WORK. Ever. If you want to cherry-pick higher-numbered packages from post-stable on a stable system, use backports. Never install a binary package from a future release.
