경로변경을 안하고 그대로 진행하니 캐싱 삭제 안됨.  

$ git filter-branch --index-filter 'git rm -r --cached --ignore-unmatch modules/sudo' --prune-empty --tag-name-filter cat -- --all

문제가 발생한 커밋번호와 디렉토리 재확인

$ git ls-tree <오류가 발생하는 커밋 해쉬넘버>

인덱스 추가와 커밋이 안되서 진행안됨

$ git filter-branch --index-filter 'git rm -r --cached --ignore-unmatch Chapter06/Chapter06' --prune-empty --tag-name-filter cat -- --all

인덱스 반영

$ git add .

커밋 

$ git commit -m "원하는 커밋 메세지"

경로 제대로 반영하여 재시도하니 정상처리 된 후 push 진행.

$ git filter-branch --index-filter 'git rm -r --cached --ignore-unmatch Chapter06/Chapter06' --prune-empty --tag-name-filter cat -- --all

$ git push

 

 

큰 도움을 준 포스팅
I was able to finally solve this issue. Here is what I did to solve it:
In article https://help.github.com/articles/remove-sensitive-data there is a heading for Purge the file from your repo. I following their example for removing the Rakefile but used the problematic folder instead:
git filter-branch --index-filter 'git rm -r --cached --ignore-unmatch modules/sudo' --prune-empty --tag-name-filter cat -- --all
Since the problematic tree was a folder I added -r to the command. The result was a cleanup of all the commits for the sudo modiles and thus, object 15abe3addde5ad5f7d25e8f0f220d2e9faf3cb22 disappeared! After a commit of the changes, the push was successful. I was able to later re-add the broken module without issue.
