Did you check docs and existing issues?

Neovim version (nvim -v)

NVIM v0.11.1

Operating system/version

nixOS(unstable)

Describe the bug

Fugit2 seems to be unable to sign commits using an ssh key with the bitwarden ssh agent

Steps To Reproduce

1. install bitwarden and enable the ssh agent
2. SSH_AUTH_SOCK=/path/to/bitwarden/ssh.sock
3. Create ssh key in bitwarden
4. Configure github to use that ssh key for signing commits
5. copy pubkey into the .ssh dir
6. try to make a commit using fugit2

Expected Behavior

The expected behavior would be for fugit2 to try to use that ssh key and get a prompt in bitwarden to allow that usage of the ssh key, like it does whenever you try to push/pull to/from a repo

Did you run ssh-add

[FKouhai]

yeah, I mean this works using lazygit, im not going to deny that the ssh agent of bitwarden needs some work but with lazygit it works

[SuperBo]

I will test bitwarden in the weekend, please wait for my update 👍

[FKouhai]

to add a bit more of info, it does use the bitwarden ssh agent to push and pull commits

[SuperBo]

@FKouhai sorry, I can't test it now, Bitwarden doesn' work correctly on my Mac.

git config gpg.format ssh
git config --global user.signingkey "<YOUR_PUBLIC_KEY>"

• ssh-add -L
