Adding the repositories and trying to update apt in WSL with Ubuntu 18.04 LTS reports 404 Not found on some URLs even though the URLs work in a browser.

Summary

Steps to reproduce

I am using WSL with Ubuntu 18.04 LTS and the guide at:

https://develop.openfoam.com/Development/openfoam/-/wikis/precompiled/windows

and in particular:

https://develop.openfoam.com/Development/openfoam/-/wikis/precompiled/debian

I am doing:

curl https://dl.openfoam.com/add-debian-repo.sh | sudo bash

and adding trusted=yes to:

deb [trusted=yes arch=amd64] https://dl.openfoam.com/repos/deb bionic main

/etc/apt/sources.list.d/openfoam.list

(This fixes another problem with the repositories. You can see the problem by removing trusted=yes.)

After this, shell reports 404 on some urls when doing the sudo apt-get update even though the URL (https://downloads.sourceforge.net/project/openfoam/repos/deb/dists/bionic/main/binary-amd64/Packages?ts=gAAAAABlU0ddE33NYF2BYJCrUgKdzm3tdc4pT5s50s0bO4jq_uOT3e-imqmuDbyW9FG41PrmLX9L7rvax9Dfyt7RR5uaZ2ydbg==&use_mirror=master&r=) itself works in a browser.

Possible fixes

Based on some threads like:

https://unix.stackexchange.com/questions/148303/apt-get-install-gives-404-not-found-but-url-works

it could be a bug with apt.

Or it could be a problem with the installer script.
