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.

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。

检查是否具有读写权限。

Git错误消息具有误导性。我也遇到过类似的问题。我被添加到一个现有的项目中。我克隆了它并提交了一个本地更改。我去推，得到了ERROR: Repository not found。错误消息。

将我添加到项目的人给了我对存储库的只读访问权。他们做出了改变，我得以推动。

我需要杀死凭证帮助进程(有多个)，它在再次提供凭证后解决了这个问题。

killall git-credential-cache——守护进程

git remote rm origin
git remote add origin <remote url>

所以对我来说，我的密码有一个'(勾)，PhpStorm在发送git推送之前删除了这个字符:

在这个例子中，我的密码是_pa ' ' ssword_

Phpstorm将输出以下内容:

https://_username_:_password_@github.com/_username_/repo.git

而不是

https://_username_ _pa“ssword_@github.com/_username_/repo.git

将密码更改为不使用'字符的密码。工作! !
