Broken Pipe Error when Attaching Remote Container

[DHG18]

I am unable to attach to a remote container when SSH'd into a server through the IDE. Attaching to the container stalls in the "installing server" state, and then returns this error message:

[1810 ms] Start: Run in container: (dd iflag=fullblock bs=8192 count=7140 2>/dev/null; dd iflag=fullblock bs=1714 count=1 2>/dev/null) | tar --no-same-owner -xz -C /home/sparkuser/.vscode-server/bin/d045a5eda657f4d7b676dedbfa7aab8207f8a075_1666023339851

@Chuxel Have you seen this before?

@DHG18 Are you trying to use a Dev Container or literally the container attach capability? Is the container in Docker or Kubernetes? Also, does this repro in VS Code stable?

@chrmarti Attach has not been implemented once you've done a Remote - SSH connection yet has it? Just Dev Container support is in so far IIRC - or is it just Kubernetes that's missing per #6054? Assuming that's what is happening here, the error message here isn't great but it would explain the issue... though honestly this looks like it got farther than that.

Hey @Chuxel sorry for delayed response:

• I'm trying to use the container attach capability through the remote docker extension
• It's a docker container
• This does repro in VS Code stable

This should work. It looks like there is a problem with the ssh connection while we are sending the server bits over. Are you using a simple ssh connection or are there proxies/jumpservers involved? What is the ssh server's version?

[DHG18]

Using a simple ssh connection. ssh version: OpenSSH_9.0p1, LibreSSL 3.3.6
