Error: ssh: handshake failed: knownhosts: key mismatch

[jarbus]

Using git-bug, getting this error when I try to push to remote:

➜ git bug push
Error: ssh: handshake failed: knownhosts: key mismatch

Reported it here: MichaelMure/git-bug#929. Dev said it might be a problem with go-git. I can push and pull with regular git, so I'm wondering if git has an ssh configuration that go-git doesn't support.

See #516 for a workaround for this.

That sounds like an issue with the picked algorithm used during the SSH handshake. That should be fixed via #411.

Are you using the latest version of go-git? If you do, do may have entries in your known_hosts that are not aligned with the key you are providing.

If I'm not mistaken, that fix has not been released in a tagged version yet. git-bug currently use the latest v5.4.2.

@MichaelMure you may update to the latest version from master with:

go get github.com/go-git/go-git/v5@master

@pjbgf I'm still facing this issue after running this command and recompiling

This issue has since been solved by adding my id_rsa key to ssh-agent, which I didn't do initially because I was using a different key with github
