Ssh authentication fails [error 500] when mirroring GitHub to gitlab.com

How to Use GitLab

Hi, I trying to mirroring my repo (upstream repo: github, and the mirror one: gitlab). This idea can be achieved by “repositories mirroring” feature on gitlab.

However, I encountered problems when using mirroring feature with “ssh authentication” (it works with https password method). It always return 500 error page without further notice/error (please see my attach pics).

Here are steps to reproduce issue:

  • Give the URL of upstream repo
  • Mirror dection: PULL
  • Input host key manually: copy the “fingerprint” from upstream-repo on github
  • Copy ssh-public-key from gitlab user -> github deploy key

Version: GitLab.com Enterprise Edition [11.4.0-ee]

Did I miss something or …?
Comments are highly appreciated :slight_smile: Thanks.
