hackage-server allows uploading candidate with version which is already in the main index

Maybe a duplicate of #768?

This issue is still open and I ran into it again: https://hackage.haskell.org/package/system-fileio-0.3.16.5/candidate

I would think that a check whether the same version is already published would be easy to implement.

Hi! Now you mention it I do recall that, it completely slipped my mind shortly after... To be honest, I'm quite busy with life at the moment, and I don't think I'll get a chance to look at it, sorry.
