Fetching proton's sniper sdk Manifest requires authorization, Rendering containers within the build script completely useless.

Build script fails with
docker: Error response from daemon: Head "https://registry.gitlab.steamos.cloud/v2/proton/sniper/sdk/manifests/0.20230509.49493-2": EOF.
On Podman, the story is basically the same.
Looking at what it's fetching, it seems like the URL Requires authentication.

I've tried the build script on multiple machines and different networks and vpns, and all of them did the same exact thing.

Hello @Weather-OS, this reads like an issue that should be evaluated by a Steam runtime dev before a Proton dev, so I've transferred this issue report to the steam-runtime issue tracker.

Fetching with wget does indeed fail with 401 Unauthorized (Gitlab's integrated registry is weird like that), but I can't reproduce inability to pull the image with podman. Steps tried:

• boot a Ubuntu 22.04.2 live image (to make sure I don't have any special authentication configured)
• click on "Try Ubuntu" when prompted
• open a terminal
• sudo sed -i -e 's/main/main universe/' /etc/apt/sources.list
• sudo apt update
• sudo apt install podman
• podman pull registry.gitlab.steamos.cloud/proton/sniper/sdk:0.20230509.49493-2
• image downloads successfully
