Like how on Debian’s website, you can find their ISO’s and other related files in this very simple file browser layout which looks kind of old but I want that, know any projects or way to set something like that up? The modern self-hosted stuff just does not seem simple enough, and both aesthetically and from a functional perspective I would like something like what debain does with their own files. I also want it to be reliable, for some reason, with both immich and nextcloud, a relative of mine was unable to download alot of photos without the download not even starting on Nextcloud, or it stopping 30% of the way on immich, if reliable downloads necessitate a desktop app with their own unique file exchanging protocol I would be ok with that too (willing to compromise with the desired aesthetic and minimalist design)
The ideal thing is the thing here: https://cdimage.debian.org/debian-cd/
Read-only, or the ability to edit filenames & upload files?
Read only: as per other answers here, basically any HTTP server. The easiest one I know would be darkhttpd, because it requires no config files and can be run without root.
