Failed to connect to the remote extension host server when using Cursor Fork

[ashkan-leo]

Hi folks,

When connecting with VS Code Version: 1.93.1 I get the error

Failed to connect to the remote extension host server (Error: WrappedError(WrappedError { message: "error checking server integrity", original: "failed to run command \"/home/ashkan/.vscode-server/cli/servers/Stable-38c31bc77e0dd6ae88a4e9cc93428cc27a56ba40.staging/server/bin/code-server --version\" (code 127): Could not start dynamically linked executable: /home/ashkan/.vscode-server/cli/servers/Stable-38c31bc77e0dd6ae88a4e9cc93428cc27a56ba40.staging/server/node\nNixOS cannot run dynamically linked executables intended for generic\nlinux environments out of the box.

My configursion is:

services.vscode-server.enable = true;
services.vscode-server.enableFHS = true;

Any advise on how to fix?

VS Code Version: 1.93.1

This seems like a relatively old version. Are you sure that's the correct version number, and if so, have you tried removing the .vscode-server folder, then restarting the user service ?
Also, does it work without FHS?

Thanks for the quick reply. You are right. Updating VS Code and deleting the .vscode-server folder fixed the issue. 👍

A side note: using Cursor (a fork of VS Code) the problem persists. Here is the cursor version

It might be that it stores lts data in another folder than .vscode-server, in which case that has to be specified in the corresponding option of the module IIRC, and that might work but I'm not sure.

[ashkan-leo]

Do you know how to figure out where it stores the data?
But if it is storing it somewhere else, then how come it is producing this error?

That's the error you get from not patching.
The path is in the error: $HOME/.cursor-server

[ashkan-leo]

Ah you're right. I got confused.
Is it possible to have this installed in both the vscode-server and cursor-sever directories?
I did try to copy over all the files in vscode-server to cursor-server but that did not help and is resulting in the same error.

No it's not supported at the moment.
I would be willing to merge a PR adding support for taking both a path and a list of paths as path option if that doesn't increase the code complexity too much.
