Answer 1

In your screen shot you can see 3 commits, two commits are connected, test and remove test, but then your newest commit does not have a parent, hence no related histories.

Option 1 ( origin/master has no useful code)

Judging by the commit messages, you have an empty repo before your latest commit. In this situation, I would force replace what is on remote by doing git push -f .

Please note this will delete the commits labeled test and remove test .

Option 2 ( Keep origin/master )

Use git cherry-pick those commits into your local master. Always do this oldest to newest.

git cherry-pick <commit hash>
