Thanks for the report @farwydi - can you post your ~/.netrc file, with any sensitive information redacted out?

[alexcb]

I can replicate this if I create an invalid netrc file; e.g.

echo "invalid netrc file" > ~/.netrc; SSH_AUTH_SOCK="" ./build/linux/amd64/earthly github.com/earthly/hello-world:main+hello

[alexcb]

#981 should fix this issue.

[farwydi]

-> % cat ~/.netrc

I don't remember why I need this file, but I just deleted it and it worked.
Thank you for such a quick response!
