What I can do to resolve "1 commit behind master"?

After pushing I've been seeing this message at remote repository:

1 commit behind master.

This merge has conflicts that must be resolved before it can be committed.

To manually merge these changes into TA20footerLast run the following commands:

git checkout 7c891f50c557

Note: This will create a detached head!

git merge remotes/origin/master

Before you begin, if you are uncomfortable with a command line, you can do all the following steps using SourceTree, GitExtensions, GitHub Desktop, or your favorite tool.

To solve the issue, you might have two scenarios:

1. Fix only remote repository branch which is behind commit

Example: Both branches are on the remote side

ahead === Master branch

behind === Develop branch

Solution:

1. Clone the repository to the local workspace: this will give you the Master branch, which is ahead with commit

   git clone repositoryUrl
   

2. Create a branch with Develop name and checkout to that branch locally

   git checkout -b DevelopBranchName // this command creates and checkout the branch
   

3. Pull from the remote Develop branch. Conflict might occur. if so, fix the conflict and commit the changes.

    git pull origin DevelopBranchName
   

4. Merge the local Develop branch with the remote Develop branch

     git merge origin develop
   

5. Push the merged branch to the remote Develop branch

     git push origin develop
   

2. Local Master branch is behind the remote Master branch

This means every locally created branch is behind.

Before preceding, you have to commit or stash all the changes you made on the branch behind commits.

Solution:

1. Checkout your local Master branch

   git checkout master
   

2. Pull from remote Master branch

   git pull origin master
   

Now your local Master is in sync with the remote branch. As a result of the above command, other local branches branched from the previous local Master branch are not in sync. To fix that:

1. Checkout the branch that is behind your local Master branch

   git checkout BranchNameBehindCommit
   

2. Merge with the local Master branch

   git merge master  // Now your branch is in sync with the local Master branch
   

If this branch is on the remote repository, you have to push your changes.

    git push origin branchBehindCommit

1. Clone your fork:

   • git clone [email protected]:YOUR-USERNAME/YOUR-FORKED-REPO.git

2. Add remote from original repository in your forked repository:

   • cd into/cloned/fork-repo
   • git remote add upstream git://github.com/ORIGINAL-DEV-USERNAME/REPO-YOU-FORKED-FROM.git
   • git fetch upstream

3. Updating your fork from original repo to keep up with their changes:

   • git pull upstream master
   • git push

If your branch is behind by master then do:

git checkout master (you are switching your branch to master)
git pull 
git checkout yourBranch (switch back to your branch)
git merge master

After merging it, check if there is a conflict or not.
If there is NO CONFLICT then:

git push

If there is a conflict then fix your file(s), then:

git add yourFile(s)
git commit -m 'updating my branch'
git push

If the message is "n commits behind master."

You need to rebase your dev branch with master. You got the above message because after checking out dev branch from master, the master branch got new commit and has moved ahead. You need to get those new commits to your dev branch.

Steps:

git checkout master
git pull        #this will update your local master
git checkout yourDevBranch
git rebase master

there can be some merge conflicts which you have to resolve.

Suppose currently you are in your branch myBranch
Do the following :-

git status

If all changes are committed

git pull origin master

If changes are not committed than

git add .

git commit -m"commit changes"

git pull origin master

Check if there are any conflicts then resolve and commit changes

git add .

git commit -m"resolved conflicts message"

And then push

git push origin myBranch
