Git Submodule Fork Reconfigure

Git submodule pushes fail with a 403 permission denied error when you lack write access to the upstream repository. You can resolve this by forking the upstream submodule and reconfiguring your remotes to point to your personal fork.

To fork a git submodule and regain write access, fork the upstream repository via gh, rename the original origin to upstream, add your fork as the new origin, and push with tracking to update the remote configuration.

Forking a submodule does not remove the original upstream repository reference. The process renames the original origin to upstream, preserving it as a reference while adding your new fork as the primary origin for write operations.

To update the parent repository after reconfiguring submodule remotes, modify the .gitmodules file to reflect the new fork URL and run git submodule sync to align the local configuration with the updated remote endpoints.

The best way to fix git submodule permission issues across repositories is to systematically fork each upstream submodule, re-point the remotes to your personal forks, and update the parent repository alignment through .gitmodules and submodule sync.

You need the GitHub CLI installed because the fork creation process utilizes gh to generate your personal copy of the upstream submodule before renaming and adding the new remotes for tracking and pushing.
