How exactly did you do that? Did you upgrade to version 3 before going to v4? That is the recommended approach.

I've just loaded up the Devuan chimaera live ISO image and that command works just fine there so perhaps something went wrong with your attempted upgrade.

Is git the chimaera version?

apt policy git

Your debug output stops just before the SSL certificate verification stage so also check

apt policy ca-certificates
date # is the system clock correct?

Although I would expect an error message about the certificate failing if there was a problem there. How long did you wait?

Does the repository clone successfully if you use http instead of https?

Do you have a firewall running? If so does disabling it help?

Are you using a proxy? If so have you configured git to work with that?

Finally, is there a reason why you've posted here rather than the Devuan forums? You might get a better response there.
