我得到了同样的错误

ERROR: Repository not found.   
fatal: The remote end hung up unexpectedly

我在Github上创建了存储库，并在本地克隆了它。

我可以通过打开.git/config并删除[remote "origin"]部分来解决。

[remote "origin"]   
   url = git@github.com:alexagui/my_project.git  
   fetch = +refs/heads/*:refs/remotes/origin/*

然后我运行以下程序(再次)

git remote add origin git@github.com:alexagui/my_project.git  
git push -u origin master

这一次我可以推到存储库。

我也遇到过同样的问题，是私人回购。

做以下几点:

移除远端原点

git remote rm origin

重新添加原点，但与您的用户名和PWD与写权限在这个PVT回购

git remote add origin  https://USERNAME:PASSWORD@github.com/username/reponame.git

如果你的repo之前工作正常，突然弹出这个错误，最有可能的原因是你的git被认证为其他用户，没有访问存储库的权限。因此，为了进行推送，您所需要做的就是在git命令中指定正确的用户名和密码。所以，一个github回购的推命令看起来像:

git push https://youruser:password@github.com/user/reponame.git

用户名和密码需要进行url转义，因此@应该被%40取代，等等。

我也遇到过类似的问题。错误的凭据缓存在OS X的密钥链中。

对我来说，这些回答都没用。 我只是忘记在远程(github.com)上创建回购。所以我在网上创建了我的回购，用同样的名字，然后重新做

所以，这是整个故事:

git init ...
git add ...
git commit ...
git remote add origin git@github.com:<myName>/<myRepo>.git
git push -u origin main

ERROR: Repository not found.
fatal: Could not read from remote repository.

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

这里你需要在github.com上添加你的回购，使用相同的“myRepo”名称

git push -u origin main 

Normally it happens because the project is private and you have not rights to write it. I had the same "problem" a few times, and it was for that reason. If the project it is yours, just create a private and a public key following this link: https://docs.github.com/en/github/authenticating-to-github/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent and add them to the "SSH and Key" section on gitHub, then you will be able to push to the repo. In the other hand if the project it is not your, ask the owner to give you the rights for it.
