Binary dependency on Linux always fails to download with NSURLErrorTimedOut

[judemille]

Description

I'm writing an experimental package in which I would like to use SwiftLint. Given it's cross-platform, I figured I would use it via SwiftPM. SwiftLint has a binary dependency in its manifest for the case in which it is being run on a Mac, so it can use a pre-compiled version. Whether this is a good idea is a different question, but it puts me in a bad position. I can download the file manually, but SwiftPM hangs for a while and errors.

Expected behavior

My package gets its dependencies and builds.

Actual behavior

Steps to reproduce

1. Create a package depending on SwiftLint.
2. Attempt to build it on Linux.

Swift Package Manager version/commit hash

Swift Package Manager - Swift 5.10.0-dev

Swift & OS version (output of swift --version ; uname -a)

Swift version 5.10-dev (LLVM e8e5be8d5b39f46, Swift 99e9db868aefd99)
Target: x86_64-unknown-linux-gnu

(This also occurs on 5.9.2. I switched to 5.10-dev to see if it was fixed.)

Linux J-failbox-AR 6.6.9-1-ck-generic-v3 #1 SMP PREEMPT_DYNAMIC Tue Jan 2 15:26:54 EST 2024 x86_64 GNU/Linux

My distro should be irrelevant to the problem at hand here. I can attempt to recreate on another distro if necessary.

Further information: this also occurs when trying to build SwiftLint alone in its tree.

This issue is topically also blocking SwiftLint's distribution via Homebrew.

I would insert some instrumentation to get a better sense as to what is actually causing this issue, but I'm not particularly up for trying to build the entirety of Swift from source in debug mode, and then figuring out where to actually put breakpoints to inspect the environment.
