unable to to clone public GitLab repos using SSH

[heygarrett]

Description

I get an SSH authentication error when attempting to clone a public repo from GitLab (I've tried multiple repos):

~/d/repos/forks
❮ jj git clone --colocate git@gitlab.com:ibhagwan/fzf-lua.git
Fetching into new repo in "/Users/garrett/dev/repos/forks/fzf-lua"
Error: authentication required but no callback set; class=Ssh (23); code=Auth (-16)
Hint: Jujutsu uses libssh2, which doesn't respect ~/.ssh/config. Does `ssh -F /dev/null` to the host work?

I am using 1Password as my SSH agent, and I am able to clone from GitHub, as well as a private, hosted GitLab instance, without issue.

Steps to Reproduce the Problem

1. Grab an SSH clone link from a public repo on GitLab (I'm using fzf-lua because it's also on GitHub)
2. jj git clone <ssh-clone-link> or jj git clone --colocate <ssh-clone-link>

Expected Behavior

The repo would be cloned.

Actual Behavior

Error: authentication required but no callback set; class=Ssh (23); code=Auth (-16)
Hint: Jujutsu uses libssh2, which doesn't respect ~/.ssh/config. Does `ssh -F /dev/null` to the host work?

Specifications

• Platform: macOS 15.2
• Version: jj 0.25.0

Did the ssh command in the hint work?

You can try building from head (after #5228) and running jj config set --user git.subprocess true.

@martinvonz My mistake. It turns out I had the wrong key set up on GitLab. 🤦‍♂️
