I was trying to clone a repo and was facing this issue, I tried removing all git related credentials from windows credentials manager after that while trying to clone git was asking me for my credentials and failing with error invalid username or password. This was happening because the repo I was trying to clone was under an organization on github and that organization had two factor auth enabled and git bash probably do not know how to handle 2fa. So I generated a token from https://github.com/settings/tokens and used the github token instead of password while trying to clone the repo and that worked.

其他答案都不适合我，我可以在浏览器中查看回购，但当试图获取或做一个新的克隆时，得到了Not Found错误。出于某种原因，这解决了问题:

在浏览器中访问Github repo。 点击绿色的“代码”按钮(如下图)。 选择“使用Github桌面打开”。 Github桌面应该打开并成功获取。 你现在可以关闭Github桌面，从控制台或你选择的Git软件中获取或克隆。

〇解决方案

问题,

$ git clone https://github.com/abc/def.git
Cloning into 'def'...
remote: Repository not found.
fatal: repository 'https://github.com/abc/def.git/' not found

解决方案- 卸载凭据管理器-

abc@DESKTOP-4B77L5B MINGW64 /c/xampp/htdocs
$ git credential-manager uninstall

abc@DESKTOP-4B77L5B MINGW64 /c/xampp/htdocs
$ git credential-manager install

它的工作原理……

在我的情况下，我需要在Linux上使用Ctrl + H打开目录来查看隐藏的文档，所以我进入Git配置并在URL中取出。Git。

这可能是一个重叠的问题，你在同一时间配置不同的帐户。

试着检查:

git config user.name git config user.email

检查是否与远程回购相同。

查看repo git remote -v

这里的问题是windows凭据管理器，请去控制面板，搜索凭据管理器，并删除它关于github的所有内容
