flatpak-builder version

1.4.10

Flatpak version

1.18.0

How to reproduce

This is when building https://gitlab.gnome.org/GNOME/evolution/-/blob/master/flatpak/org.gnome.Evolution-master.json?ref_type=heads , but to make it simpler, the file contains a module reference:

		{
			"name": "libmspack",
			"cleanup": [ "/bin" ],
			"sources": [
				{
					"type": "archive",
					"url": "https://www.cabextract.org.uk/libmspack/libmspack-0.10.1alpha.tar.gz",
					"sha256": "bac862dee6e0fc10d92c70212441d9f8ad9b0222edc9a708c3ead4adb1b24a8e"
				}
			]
		},

and when I run:

flatpak-builder --disable-updates --force-clean org.gnome.Evolution-master org.gnome.Evolution-master.json --verbose

it prints at the end:

FB: Running: git cat-file -e main

Failed to download sources: module libmspack: The requested URL returned error: 403

Expected Behavior

Well, the file is downloaded. I can use wget URL, curl URL --output /tmp/FILE and also a web browser can download it, only the download made by the flatpak-builder fails with the 403. It used to work in the past, no idea when it begun to fail.

Actual Behavior

File not downloaded

Add disable-http-decompression: true to the module, it's a broken server. I tried adding an informative message recently but clearly doesn't cover every corner case. #682 has more information. I don't want to spend more time on this.
