'git remote repository contains commits unmerged into the local branch

I am using git inside netbeans IDE. I wanted to change the commit message for the most recent commit I had made. I did that, checked the amend last commit checkbox and committed it to my local repository. When I push this commit to my github repo, I get the error: git remote repository contains commits unmerged into the local branch. open output to see more information. How do I fix this ? I am new to source control. I only want to do very basic version control with my current project. Please tell me how to fix this.

Realize a pull. Then a window with the option 'merge' will appear. Do a merge and try to push it again.

Sorry for my english level

Solution 2:^[2]

Don’t use git pull, use git fetch, then git merge, then git commit and then git push.

If you can not see the file under remote in the git repository browser then first you need to pull in order to solve the above problem.
Steps:
1.Right click project > Git > Remote > Pull > then select merge option.
2.Right click project > Git > Remote > Push.
The problem should be solved by now :-)

Solution 4:^[4]

Right click your project > Git > Remote > fetch Right click your project > Git > Branch/ tag > Merge Revision Click merge Now u should be able to do the push...

Solution 5:^[5]

I would delete the repository. Recreate the repository. Please don't commit anything. Then push it after adding and committing inside NetBeans. Remember, you can create README.md, anything later.

Solution 6:^[6]

Though it's already solved. just want to post it down here. I had the same error as yours but it happened because i modified my repository in github and didn't pull it to my local repository.

you need to remote > pull and then choose rebase.

that's what i did
