如何在 WIndows 上仔细检查我的 SSH 凭据？

Question

I am a member of my company organization. SSH keys associated with my account. Nothing works as expected. I am trying to push my branch

$ git push -u origin mirispc
The authenticity of host 'github.com (140.82.121.4)' can't be established.
RSA key fingerprint is SHA256:$$$$$$$$$$$$$$$$$.
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added 'github.com' (RSA) to the list of known hosts.
ERROR: Repository not found.
fatal: Could not read from remote repository.

I cloned my comp private repo(details changed for security reasons)

origin  git@github.com:mycomp/repo-pr (fetch)
origin  git@github.com:mycomp/repo-pr (push)

I will copy just part of the ssh -Tv git@github.com due to length

Hi JHolmes! You've successfully authenticated, but GitHub does not provide shell access.
debug1: channel 0: free: client-session, nchannels 1

I am running all of these from Git Bash.

What should I try now?

Answer 1

First, make sure that https://github.com/mycomp/repo-pr does exist (meaning the case, uper or lower, of the URL is correct)

Second, check that you are correctly authenticated by GitHub through SSH:

ssh -Tv git@github.com

Third, double-check with your org admins that you are indeed a member of said organization.

On Windows, make sure you don't have a GIT_SSH environment variable set.
