`Error: HTTPClientError.remoteConnectionClosed`

[Sammcb]

Hi! I am trying to cross compile for ubuntu x86_64 and arm64 architectures. I followed the steps on the readme and cloned the repo and ran swift run swift-sdk-generator.

However, I am seeing this output:

Parsing Ubuntu packages list...
Downloading 11 Ubuntu packages...
Error: HTTPClientError.remoteConnectionClosed

Edit: And running again with verbose output:

$ swift run swift-sdk-generator -v
Building for debugging...
Build complete! (0.14s)

Looking up configuration values...

Curious if this is an issue or if I am doing something wrong. I am running this on an M1 Pro Mac on macOS Sonoma with swift 5.9. Output of uname -a: Darwin <local host>.local 23.0.0 Darwin Kernel Version 23.0.0: <date>; root:xnu-10002.1.13~1/RELEASE_ARM64_T6000 arm64 Output of swift --version:

SHA of swift-sdk-generator: 46cc742e5f28de778ebb6f061e62455e07bc3a81.

Thanks!
