macOS - vscode-server blob does not exist

Bug Reports

Trying to use remote ssh to connect to remote machine, the install script is trying to download this:

but it doesn’t exist:

Hi! Could you try switching to the Anysphere version of the Remote-SSH extension? You can find it in the marketplace by searching for @id:anysphere.remote-ssh – attaching a screenshot. Please let us know whether this works for you.

Hi, thank you for you answer, didn’t know that cursor made their own remote-ssh.

I’ve installed it and tried to connect to my server but I get this error:

I’ve tried locating the logs but can’t seem to find them. For context I’m on macos and trying to connect to an Alpine Linux server. Also, I have no trouble connecting and installing when using vscode with remote-ssh on the same computer and server.

Could you share the logs from the β€œRemote - SSH” output tab? Attaching a screenshot for where these can be found

Also, could you try upgrading to version 0.0.30 of the extension (if you’re on an earlier version?)

Note that I am trying to connect to Home Assistant OS. I am on the newest version and here is the logs:

Thanks for sharing – let me look into this more and see what we can do to support Alpine Linux.

7

Hi – I checked with the team, and unfortunately Alpine Linux remote hosts are not currently supported. This is because some of our internal packages are currently incompatible with musl libc, on which Alpine Linux is based. We do plan on making Cursor compatible with this setup.

In the meantime, I would recommend using a SSH sync extension, such as Remote File Sync - Visual Studio Marketplace, instead of our Remote SSH. The difference here is that Cursor will run locally, and automatically copy your files to the remote device. I realize that this experience is less than ideal, as tools like run + debug would run locally, but we’ll share when Alpine is officially supported with Remote SSH.

8

Ok, I appreciate your effort. I’ll try the sync extension for now, thanks!

9

Hi! Wanted to share that we just added support for Alpine Linux remote hosts.

You will need:

  • Cursor v0.50.5 or greater
  • The latest version of the Anysphere Remote Extension
    • Dev Containers (anysphere.remote-containers) v0.0.12 or greater, or
    • Remote SSH (anysphere.remote-ssh) v0.0.34 or greater
  • Inside your Alpine remote host:
    • bash
    • libstdc++
    • wget
    • openssh (SSH only, not required for docker), with TCP Forwarding enabled (set AllowTCPForwarding yes inside /etc/ssh/sshd_config)

Support for Alpine remote hosts is in beta. Please let us know if you run into any issues with the setup. Thanks!

10

Hey! Followed your instructions and it works like a charm, no errors. Thank you and your team for resolving this so quickly.
