I was not able to install the Samsung Unified Linux Driver Repository (SULDR) via apt under debian (maybe the repo is too old / no longer maintained) – let me know in the comments if you were able to install via the repository.

Someone made a backup on Github, so I was able to install via these *.deb files. Just quickly noted – also for me as reference in the future. Also I was able to use the Scan to PC function after installation.
