Provide a clear description of the bug
When trying to open a DevContainer project using Cursor, the process gets stuck indefinitely at the stage “Downloading VS Code Server.”
The logs show repeated attempts to download the VS Code server for commit 0781e811de386a0c5bcb07ceb259df8ff8246a50, targeting architecture linux-arm64, but it never completes.
Meanwhile, the same DevContainer setup works correctly in standard VS Code (latest stable), suggesting this is a Cursor-specific issue.
Explain how to reproduce the bug (if known)
- Open a project with a .devcontainer setup in Cursor (using Microsoft Artifact Registry as the base image).
- Cursor attempts to build the devcontainer.
- It reaches “Installing VS Code Server” and gets stuck at:
1325 ms] Installing VS Code Server for commit 0781e811de386a0c5bcb07ceb259df8ff8246a50
[1325 ms] Start: Run in container: /bin/sh
[1325 ms] Start: Downloading VS Code Server
[1325 ms] 0781e811de386a0c5bcb07ceb259df8ff8246a50 linux-arm64 stable
- It never proceeds beyond this point (even after more than 1 hour).
Here’s my decontainer setup:

Yes, I really rely on DevContainer for my development flow
