Please answer the following before submitting your issue:

Note: Please include any substantial examples (debug session output, stacktraces, etc) as linked gists.

  1. What version of Delve are you using (dlv version)? Delve Debugger Version: 1.8.2
  2. What version of Go are you using? (go version)? go version go1.16.13 darwin/amd64
  3. What operating system and processor architecture are you using? Darwin 192.168.0.102 19.4.0 Darwin Kernel Version 19.4.0: Wed Mar 4 22:28:40 PST 2020; root:xnu-6153.101.6~15/RELEASE_X86_64 x86_64
  4. What did you do? connect mac use vscode through vscode remote-ssh extension，the below is launch.json that can't work， { "name": "gotest", "type": "go", "request": "launch", "dlvFlags": [ "--log", "--log-output", "dap,debugger,fncall,rpc,debuglineerr,lldbout,minidump,gdbwire" ], "program": "${file}", "mode": "auto" }
  5. What did you expect to see? can debug like local
  6.

I am hitting same issue.

Another found might be related: If I try to manually start a dlv --headless server through the terminal established by remote development, I got same error

This looks like it may be a problem running the lldb debugserver. We've seen similar issues in the past (e.g. #1637), but in this case it looks unrelated to Apply M1 (since you're on amd64).

We'll discuss in our weekly triage meeting, but poking around for this error returned this: https://lists.llvm.org/pipermail/lldb-dev/2019-July/015264.html

Are you able to try running delve from a graphical session, to see if you get an authentication popup?

Timed out in state WaitingForInfo. Closing.
