It's empty for kali-bleeding-edge, is this expected? https://repology.org/log/3294157

@AMDmi3 Yes it's empty, and it's expected that it can be empty.

kali-bleeding-edge only contains packages that are automatically updated by the Kali bot, and I think there's no package in scope for the bot in kali-bleeding-edge, at the moment. This might change in the future.

I noticed that non-free is also empty for kali-bleeding-edge: http://http.kali.org/dists/kali-bleeding-edge/non-free/binary-amd64/

If that's a problem that a component is empty, feel free to remove non-free and non-free-firmware for kali-bleeding-edge then.

And thanks again for maintaining repology
