Getting Askpass for every action even when its not needed

[Akira-Kuru]

I added ssh to the ssh-agent so I don't have to constantly add the password to the sourcegit but it keeps giving me the askpass prompt for pull, push, fetch and commits.

Even when deleting branches I also get the askpass prompt.
What I find wild with deleting branches is that if you cancel the askpass prompt, the branch gets deleted either way.

This window is launched by ssh not SourceGit:

sourcegit/src/Commands/Command.cs

Lines 167 to 175 in 0a74dd6

	// Force using this app as SSH askpass program
	var selfExecFile = Process.GetCurrentProcess().MainModule!.FileName;
	if (!OperatingSystem.IsLinux())
	start.Environment.Add("DISPLAY", "required");
	start.Environment.Add("SSH_ASKPASS", selfExecFile); // Can not use parameter here, because it invoked by SSH with `exec`
	start.Environment.Add("SSH_ASKPASS_REQUIRE", "prefer");
	start.Environment.Add("SOURCEGIT_LAUNCH_AS_ASKPASS", "TRUE");

Make sure you have enable the AddKeysToAgent configuration in ~/.ssh/config

Host *
  AddKeysToAgent yes

Hi, I have same problem, mint, manjaro. All time when I want to do some git actions - always prompt for ssh key password

➜  ~ cat ~/.ssh/config
Host *
  AddKeysToAgent yes

If your private key has a passphrase, each time you use it, SSH will ask for its password. You can use ssh-keygen -p -f <private_key> to reset its password to empty.

I added

Host *
  AddKeysToAgent yes

and the ssh-agent is running on my terminal, however I still receive the AskPass prompt.

I even tried it out with a file creating, deleting, committing and pushing over terminal which worked without any issue.
Then the same approach with sourcegit and I still get the prompt.

Then I added this code below in ~/.ssh/config and attempted the same process again.

Host github.com
  AddKeysToAgent yes
  IdentityFile ~/.ssh/id_work
  BatchMode yes

This time, sourcegit decided not to commit or push and simply gave me a "Permission denied (publickey)." error even though it works on the terminal. Not giving me any prompt anymore because of BatchMode yes.

I would also not take the ssh-keygen -p -f <private_key> approach since you are not keeping your SSH Key secure this way.

If this was an SSH issue then it would have also happened on the Terminal which it didn't.

This may be because the private_key_file is passed into the SSH command every time in the code:

sourcegit/src/Commands/Command.cs

Lines 175 to 179 in 0a74dd6

	// If an SSH private key was provided, sets the environment.
	if (!start.Environment.ContainsKey("GIT_SSH_COMMAND") && !string.IsNullOrEmpty(SSHKey))
	start.Environment.Add("GIT_SSH_COMMAND", $"ssh -i '{SSHKey}'");

Later, I'll check if there is a better way to handle the SSH connection.

I test this on Windows platform that when installing GIT, using external openssh (without using the built-in SSH) does not have such problems.

Makes sure ssh-agent service is running

BTW, on which system do you encounter this problem?

[piotr-fraczek]

BTW, on which system do you encounter this problem?

I use Linux: Manjaro, Mint, Ubuntu distributions

On Windows 10/11 this problem not exists :)

BTW, on which system do you encounter this problem?

I use Linux: Archlinux & Windows 11.

This happened so far only on Archlinux but I will check Windows later today.

I've test this on Ubuntu. After manually add keys to ssh-agent, it will not ask me for passphrase any more.

eval `ssh-agent -s` # Makes sure `ssh-agent` started
ssh-add <private_key_file> # The `<private_key_file` is the same one with `SSH Private Key` of remote configuration in `SourceGit`

# Then restart `SourceGit` and try to fetch/pull/push/create commit in `SourceGit`

I think I know why.

• When I started SourceGit from the terminal session that just runs eval `ssh-agent -s` , this issue does not exists
• When I started SourceGit from other terminal sessions that have not ran eval `ssh-agent -s` , this issue appears

Maybe, SSH_AGENT_PID and SSH_AUTH_SOCK are needed by ssh command
