@mak let me know if you need any visual assets to replace the existing Debian ones. I may have missed something

@mladen.pejakovic because png has good quality/compression ratio and is the intermediate image format that I always use for reference or format conversion when required.
If they need to be in a different format just let me know.

Could you also remove the "Debain" branded wallpapers and add those pictures in the wallpapers list (that appears in the settings) :

I think I can answer this one.
Our repository is synced with Debian testing's repo. Debian is currently in a frozen state until the release of Debian 9 which should happen very soon.
After that, things will be back to normal with the rolling release until the next Debian frozen state (every 5 years?)

Also, the package python-dev cannot be installed from green :

Thanks mak!
