git问题记录
1.从http切换到ssh，github在本地pull时发生
ERROR: Repository not found.
fatal: Could not read from remote repository.
总之遇到这种问题，把key重新生成一遍在github上重新加一次。具体
https://docs.github.com/en/github/authenticating-to-github/connecting-to-github-with-ssh/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent
https://docs.github.com/en/github/authenticating-to-github/connecting-to-github-with-ssh/adding-a-new-ssh-key-to-your-github-account
Generating a new SSH key
$ ssh-keygen -t ed25519 -C "your_email@example.com"
Adding your SSH key to the ssh-agent
-
Start the ssh-agent in the background.
$ eval "$(ssh-agent -s)" > Agent pid 59566
Add your SSH private key to the ssh-agent and store your passphrase in the keychain. If you created your key with a different name, or if you are adding an existing key that has a different name, replace id_ed25519 in the command with the name of your private key file. $ ssh-add -K ~/.ssh/id_ed25519 Note: The -K option is Apple's standard version of ssh-add, which stores the passphrase in your keychain for you when you add an ssh key to the ssh-agent. If you chose not to add a passphrase to your key, run the command without the -K option. If you don't have Apple's standard version installed, you may receive an error. For more information on resolving this error, see "Error: ssh-add: illegal option -- K."
Copy the SSH public key to your clipboard.
If your SSH public key file has a different name than the example code, modify the filename to match your current setup. When copying your key, don't add any newlines or whitespace.
$ pbcopy < ~/.ssh/id_ed25519.pub
注意：因为我本地要上传两个github的账号，所以还必须在~/.ssh目录下增加config配置,不同key针对不同账号，把相应zjhgx.pub里面内容拷贝到github setting里的ssh and gpg keys.
1 Host zjhgx163.github.com 2 HostName github.com 3 PreferredAuthentications publickey 4 IdentityFile ~/.ssh/zjhgx163 5 6 Host zjhgx.github.com 7 HostName github.com 8 PreferredAuthentications publickey 9 IdentityFile ~/.ssh/id_ed25519
2. 不知怎么回事，sshkey添加到github过两天，再git pull 发现permission denied(public key).又得
eval "$(ssh-agent -s)" ssh-add ~/.ssh/zjhgx
3. 又出现了可怕的 ERROR: Permission to zjhgx163/proxy.git denied to zjhgx.
这次是zjhgx163上新建了个仓库，然后本地clone下来想提交时又出现了这个问题。我的golbal user.name 是zjhgx，但是把这个工程的local user.name改成zjhgx163
也没用。把zjhgx账户上的key给删了就好了，不知道是什么缘故。我猜是以前误操作把zjhgx163的key加到了zjhgx账户上，这样就有一个key在zjhgx，zjhgx163账户上都存在过。然后github上有个bug把以前的缓存在那里，导致虽然已经把那个key删了但还是出问题？
4. 如果出现“
ERROR: Repository not found.
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
”
需要把key重新加入到agent “ssh-add --apple-use-keychain ~/.ssh/zjhgx163”
===========================
上面问题其实是两个github的account配置错误，remote url 和config配的域名不匹配
Host github.com-zjhgx163
HostName github.com
PreferredAuthentications publickey
AddKeysToAgent yes
UseKeychain yes
IdentityFile ~/.ssh/zjhgx163
Host github.com-zjhgx
HostName github.com
PreferredAuthentications publickey
AddKeysToAgent yes
UseKeychain yes
IdentityFile ~/.ssh/id_ed25519y
相应的，remote url应该配置成，黑体字部分要匹配
git remote set-url origin git@github.com-zjhgx:zjhgx/cheap-java.git
git remote set-url origin git@github.com-zjhgx163:zjhgx163/cheap-vue.git
5. 想用
brew install --cask mark-text 结果
Error: Failure while executing; `git clone https://github.com/Homebrew/homebrew-cask /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask --origin=origin` exited with 128.
得启用代理
git config --global http.proxy 'socks5://127.0.0.1:1081'
git config --global https.proxy 'socks5://127.0.0.1:1081'
安装结束后
git config --global --unset http.proxy
git config --global --unset https.proxy
6. ex_exchange_identification: Connection closed by remote host
fatal: Could not read from remote repository.
最近出现这个问题，需要用https来连接ssh，把config文件改下：注意黑体字部分，
Host github.com-zjhgx163 HostName ssh.github.com Port 443 User zjhgx163 # PreferredAuthentications publickey # AddKeysToAgent yes # UseKeychain yes IdentityFile ~/.ssh/zjhgx163 Host github.com-zjhgx HostName ssh.github.com User zjhgx Port 443 # PreferredAuthentications publickey # AddKeysToAgent yes # UseKeychain yes IdentityFile ~/.ssh/id_ed25519 ~
在修改前先测试一下：
To test if SSH over the HTTPS port is possible, run this SSH command: $ ssh -T -p 443 git@ssh.github.com > Hi USERNAME! You've successfully authenticated, but GitHub does not > provide shell access.
