How can I solve the issue of![rejected]main->main(non-fast-forward) in git repository?

 In the context of DevOps, the error message of ![rejected]main->main(non-fast-forward) usually refers that there are conflicts with the current state of the remote branch which are leading you to loss of commit history or the integrity of the data.

Here are the steps given for troubleshooting this particular issue:-

Understanding the issue well

First, try to read the situation carefully and understand the issue well. These types of errors generally occur when your history of the commit in the remote branch has been diverged from your local branch.

Fetch and rebase

To resolve this particular issue and push your changes, you would need to fetch the changes from the remote repository and then try to rebase your local changes onto the top of the remote branch which is updated.

Git fetch origin main # Fetch the latest changes from the remote main branch

Git rebase origin/main # Rebase your changes on top of the updated main branch

Resolve the conflicts

During the process of rebasing if there are conflicts between your changes and the remote changes then try to remove it by using the command “git diff”.

Complete the rebase processes

After resolving the issue of conflicts continue the process of rebase by using the following command:-

Git rebase –continue # Continue the rebase after resolving conflicts

Push changes

Once the rebase process is completed without conflicts, you can push your changes by using the following command:-

Git push origin main # Push your changes to the remote main branch
