Couldn't add remote: remote origin already exists

This error message usually occurs when you try to add a remote repository with a name that already exists. To resolve this issue, you can either change the name of the new remote repository or remove the existing one.

If you want to change the name of the new remote repository, you can use the following command:

git remote rename origin <new_name>

Replace `<new_name>` with the desired name for your remote repository.

If you prefer to remove the existing remote repository, you can use the following command:

git remote remove origin

After that, you can add the new remote repository using the `git remote add` command.

Remember to adapt these commands according to your specific situation.
