Why does git push -u origin return Repository not found?

Question

git

There are several files in the directory in which I work. I execute the commands in sequence:

git init
git add --all
git commit -m "init"
git remote add origin [email protected]:acc/repo.git
git push -u origin

The last command returns:
ERROR: Repository not found.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

Why does it occur and how to solve it?

Answer 1

There was a problem with ssh - the same key was saved in another github account.
