Git is a popular version control system that can easily manage file and code versions in software development. However, sometimes when pulling code from a git repository, verification failure occurs, which may result in failure to pull the code or pulling the wrong code. This article will introduce some common reasons for verification failure and solutions.
1. Reasons for verification failure
SSH key is a public key encryption technology used to verify users and git Communication between servers. If the SSH key is set incorrectly, it may cause authentication failure. Common errors include: not setting the SSH key correctly, using an invalid SSH key, or the SSH key does not match the SSH key stored on the server.
When pulling code from the git warehouse, you need to provide a valid account information (such as user name and password). If the account information is incorrect, verification will fail. Common errors include: incorrect username or password, not using the correct authorization token, etc.
Sometimes, verification failure is caused by a server error. For example, the server may have stopped serving, or it may be configured to deny connections from some IP addresses. These situations usually cause error messages when trying to connect to the server.
2. Solution
The SSH key is a key associated with the account and is used for verification Communication between users and git server. When interacting using the SSH protocol, the SSH key must be set correctly. You can check whether the SSH key is set correctly through the following steps:
(1) Open Git Bash or terminal.
(2) Enter the following command: ssh -T git@git server (such as: ssh -T git@github.com).
(3) If the SSH key is set correctly, the system will display a prompt message and you can proceed further; otherwise, the user will be prompted with an error message.
When pulling code from the git repository, you need to provide valid account information. If the account information is incorrect, verification will fail. You can check whether the account information is correct by the following methods:
(1) Use the following command to check the stored git credentials: git config --list.
(2) If these credentials are incorrect, or there are no credentials: Use the following commands to configure the correct credentials: git config --global user.name "your username" and git config --global user. email "your email address".
(3) If the credentials still don't work, you can try using a Personal Access Token (PAT) or SSH key instead of the username and password. In this case, a PAT or SSH key needs to be provided to the git server. Before switching to using PAT or SSH keys, make sure they are set up correctly. Instructions on how to set up or generate a PAT/SSH key can be found in the documentation on the git server.
If you have checked the account information and SSH key, but still cannot pull the code from the git server, you should check the status of the git server. The following are some common server status problems:
(1) Server failure: When connecting to the git server, if you see an error message, it means that the git server may have failed. In this case, you can wait until the server is fixed and try to pull the code from the server again.
(2)IP is banned: If the IP address is banned, the connection may fail. You can contact the git server administrator to solve this problem.
Summary
Verification failures are a common problem when pulling code from a git repository, but most verification failures can be solved by checking SSH keys, checking account information, or checking server status. . If you still encounter a problem that cannot be solved, please refer to the git documentation or contact the administrator of the git server for help.
