Reasons and solutions for git pull failure [Summary]

When using Git for collaborative development, the git pull command is often used to update the code of the remote warehouse to the local one. However, sometimes failure occurs when executing the git pull command. You may encounter the following common situations:

The remote code library does not have permission

The git pull command will pull data from the remote repository and attempt to merge, but if there is no permission to access the remote code repository, the command will fail. At this point, we can check that we have the correct SSH keys or HTTPS access authorization, or contact the maintainer of the repository for more information.

Conflicts in the local workspace

When executing the git pull command, you may encounter conflicts in the local workspace. This is usually caused by changes or commits that occurred between the remote repository and the local repository. In this case, we can use the git status command to see which files have conflicts, then manually resolve these conflicts and resubmit.

Changes have occurred in the upstream repository

In collaborative development, the upstream repository (usually the maintainer of the code base) may update the code base because new code is added or modified. If there is no git fetch to synchronize the changes in the remote warehouse before the git pull command is executed, you may encounter git pull failure. At this time, we can solve this problem by executing the git pull command after the git fetch command.

The remote repository does not exist

If the remote repository using the git pull command does not exist, the command will also fail. This may be because the remote repository name entered before executing the command was misspelled, the remote repository has been deleted, or you do not have access rights. In this case, we can solve the problem by checking the spelling, contacting the maintainer of the code base, or importing a new remote repository.

The above are common git pull failure situations. If you encounter other problems, you can solve them by checking the Git documentation or asking other Git users. Of course, in order to avoid git pull failure, we recommend that you be more careful when using Git for collaborative development and do not operate at will.
