Can not use attach cursor

[GJ_K]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I’m running Docker inside WSL2, not using Docker Desktop on Windows.

This setup has been working perfectly fine until recently:
I was able to attach to running containers from Cursor without issues.

However, now Cursor fails to attach, while VS Code still works with the exact same setup.

Steps to Reproduce

I just try to attach container cursor

Expected Behavior

Cursor should behave similarly to VS Code Remote / Dev Containers:

Detect and use the WSL environment
Invoke docker inside WSL, not on the Windows host
Allow attaching to containers started in WSL

This used to work previously, so this feels like a regression or a recent internal change in how Cursor resolves Docker.

Yes - Cursor is unusable

Thanks for the detailed report. This has been flagged to the extensions team for investigation.

As a potential workaround, try downgrading the Dev Containers extension to v1.0.24 (Extensions → Dev Containers → gear icon → Install Another Version). A similar attach issue was resolved this way in this thread. Let us know if that helps!
