``Failed to retrieve list of SSH authentication methods: Failed getting response`` when key not present in ssh agent

[ysalmon]

https://github.com/gitahead/gitahead/issues/583 is still happening.

I recently added a new remote to a repository and Gittyup gives the aforementioned error when pulling or pushing to it when the corresponding ssh key has not already been added to the ssh agent. However if the key is loaded in the agent, everything runs fine.

Other repos do not exhibit this behaviour (I had problems with Gittyup not dealing with ssh keys properly in the past but these had gone), including some of them that use the exact same ssh key. Invoking git pull from the command line correctly gives a prompt for the password of the private key. ~/.ssh/config explicitly states which key is to be used.

The URL for the remote is of the form git+ssh://user@server:nonstandardport/path/to/.git (the remotes of the other repos are not, so this might be the reason).

OS : KUbuntu 20.04 with gnome-keyring as agent. Gittyup : release version of master from yesterday.
