How to "resolve fatal: Not a git repository"?

Question

I was trying to remove one sub-module from the project

Tried rm -rf .git/modules/submodulePath

After that I am having the issue

fatal: Not a git repository

Answer 1

These two files contains absolute submodule path:

{submodule}/.git
.git/modules/{submodule}/config

So, if you moved the repo, the absolute path in these two files are not valid, and cause the 'not a git repository' error. Just fix these files manually.

Update:

1. Delete the relevant section from the .gitmodules file. You can use below command:

   git config -f .gitmodules --remove-section "submodule.submodule_name"
   

2. Stage the .gitmodules changes

   git add .gitmodules
   

3. Delete the relevant section from .git/config. You can use below command:

   git submodule deinit -f "submodule_name"
   

4. Remove the gitlink (no trailing slash):

   git rm --cached path_to_submodule
   

5. Cleanup the .git/modules:

   rm -rf .git/modules/path_to_submodule
   

6. Commit:

   git commit -m "Removed submodule <name>"
   

7. Delete the now untracked submodule files

   rm -rf path_to_submodule
