It was a quiet Saturday morning. I was trying to connect to my Raspberry Pi 5 (srv01) using Cursor's Remote SSH. But instead of a warm terminal welcome, I was met with a cold, hard failure.
The Cursor Remote-SSH connection. It wouldn't start. No heartbeat. Just a "404" error in the logs that seemed to point to a missing server artifact.
The internet pointed a finger at a common culprit: Architecture Mismatch. The forum threads were buzzing with tales of 32-bit userlands on 64-bit kernels causing a 404 Not Found when Cursor tried to fetch the server artifact (cli-linux-armhf.tar.gz).
