I’m trying to get a private repo which references numerous private submodules working. I’m using ssh and cannot use https to clone them due to GitHub’s new restriction. I have access to all private submodules and have added my public keys to GitHub. I can clone the repo, can initialize and sync the submodules but when I try
git submodule update --recursive , I get fatal: clone of '[email protected]:user/repo.git' into submodule path 'path/to/main/module' failed . Is there a solution or workaround for this?

All repo entries in both .git/config and .gitmodules are ssh links

Any help would be much appreciated!

I tried:
generating a pass-less ssh key
running the command with sudo — get the same error but with “(public key)” added to the end. The public key on my computer matches the one on GitHub.
