Well, This method and technique worked fine for me: 
Inside the .git folder of your project directory, change these files: 
1 -> configs file 
  -> open it up 
  -> change the ref URL to the remote one. 
 (You must also set your remote origin 
  branch the same as the local 
  branch here inside this file. e.g: remote: main, local: main
 ) 
2 -> git fetch 
3 -> .git 
  -> refs 
  -> heads && remotes folder 
  -> make sure both in files, origins are the same inside both heads and 
    remotes folders. e.g: main or master
4 -> .git 
  -> refs 
  -> remotes 
  -> main 
  -> open it up: 
   Copy the content and paste it inside the main file of the heads 
   folder.

Finally: 
Git fetch && git pull && git push 

您可以重命名(更改远程存储库的URL)使用:

git remote set-url origin new_URL

new_URL可以像https://github.com/abcdefgh/abcd.git一样

太永久删除远程存储库使用:

git remote remove origin

您可以进入。git文件夹，无需使用命令即可编辑配置文件。

使用实例移除遥控器。

git remote remove origin

添加遥控器。

git remote add origin yourRemoteUrl

最后

git push -u origin master

你可以试试这个，如果你想删除原点，然后添加它:

git remote remove origin

然后:

git remote add origin http://your_url_here

如果你坚持要删除:

git remote remove origin

或者如果您使用的是1.7.10或更高版本的Git

git remote rm origin

但卡豪威尔的答案更好。
