I'm on the latest unstable NixOS. Happy to share any other details you need

It appears to be a bug (or feature?) in NixOS (NixOS/nixpkgs#42117), and I'm unsure of how to resolve it as I'm not familiar with NixOS. This extension does nothing other than calling sudo, but if there are any fixes needed for NixOS please let me know.

I have read the GitHub issue and perhaps we can circumvent the security wrapper by calling /usr/bin/sudo instead of just sudo?

Can you try this version? It calls /usr/bin/sudo instead of sudo (which you can verify by unzipping the .vsix file in the zip).
save-as-root-1.5.1-nixos.zip

Edit: To install it you can drag and drop the .vsix file in the zip on the list of installed extensions (ctrl+shift+x) in a VSCode window while connecting to the remote machine.

Hey @yy0931

I have more insight into this. Seems sudo calls inside VSCode's terminal is failing, which is causing this to fail. This screenshot is from the integrated terminal.

Let me report it with the VSCode repo. I'll keep you posted. We'll let this issue remain open in the meantime?

So, the latest version seems to have fixed it. All good now. Thank you :)
