Hey, thanks for the report. Alpine Linux does have a few specific requirements when using Remote Containers in Cursor.

I’ll need a bit more info to debug this:

  1. Cursor version: Cursor Settings → About → Copy
  2. Error logs: Open the Output panel CMD/CTRL + Shift + U → pick Dev Containers in the dropdown → copy the errors you see when you try to open the devcontainer
  3. Architecture: x64 or ARM64?
  4. devcontainer.json: can you share your config?

Context: Alpine support was added in May 2025, but there are some requirements:

For now, please send the logs. That’ll help confirm whether this is a server download issue or something else.

sounds good. I don’t actually need Alpine support for anything. I just noticed it didn’t work, so I figured I’d let you know. you can reproduce this error 100% of the time by opening up the repro repo I have on GitHub.

You should be able to reproduce it on your end so you can get the logs there. If you can’t reproduce it on your end for some reason, let me know.
