Git Submodule - Permission Denied

I was facing the same issue. The problem was on your github repo , you might be using some old ssh key.

You need to update the current ssh key.

Steps involved are:

1. vim ~/.ssh/id_rsa.pub
2. copy the ssh key
3. Go to the github settings
4. Select the option ssh keys
5. Remove the old ssh keys not used anymore.
6. Add a new ssh key.
7. Try running the "git submodule update --recursive"

This worked for me !!

• On Windows:

In my case, it was complaining about the same issue when I was using a regular command line (Git CMD). Then I tried with Git Bash and no issue no more.
