I am doing a git fetch (also git merge master) on the remote machines. It seems random whether it will work or not. I get errors like: “error fetching identities for protocol 2: communication with agent failed” or “fatal: ‘ef’ does not appear to be a git repository\nfatal: Could not read from remote repository.\n\nPlease make sure you have the correct access rights\nand the repository exists.”

I can manually ssh into the server and run a “git fetch” 100% of the time.

In the Ansible playbook I can do a “ssh-add -l” and see the key it should be using the step before the “Could not read from remote repository.” error. The git server is Bitbucket v5.4.0.

Any ideas?
