macOS: git over ssh wrong file permissions

[aymanbagabas]

Summary

Gopass Git is not able to pull/fetch the repository. Git is not able to communicate with the ssh-agent and I keep getting this SSH error every time I try to use a Git related Gopass command. I noticed fixing the permissions fixes the problem. The password store has these permissions, directories 700, files 600, and changing them to 755 and 644 respectively fixes the issue.

Steps To Reproduce

Running any command that involves Git ex. gopass sync

Expected behavior

Git under Gopass should be able to access the ssh-agent to be able to communicate with the remote repository since I'm using git+ssh

Environment

• OS: macOS Big Sur
• OS version: Darwin Aymans-MacBook-Pro.local 20.5.0 Darwin Kernel Version 20.5.0: Sat May 8 05:10:33 PDT 2021; root:xnu-7195.121.3~9/RELEASE_X86_64 x86_64
• gopass Version: 1.12.6-git+HEAD go1.16.5 darwin amd64
• Installation method: go get github.com/gopasspw/gopass

Additional context

[aymanbagabas]

As suggested in the FAQ, setting TMPDIR didn't help PR #1899. What I ended up doing is using GIT_SSH_COMMAND environment variable and aliasing gopass to

GIT_SSH_COMMAND="ssh -oControlMaster=auto -oControlPersist=600 -oControlPath=/tmp/.ssh-%C" gopass

Did you see this: #1896 (comment) ?

Maybe you have some "leftover SSH settings" in your git config?

[aymanbagabas]

Interestingly, it turned out that the git password store git config had a long ssh command path which was causing the problem. I still don't know how and why that got set in the config. But changing the ssh command control path to /tmp/.ssh-%C in the git config solves the problem
