Fix current branch has no upstream branch

The current local branch does not track a remote branch, so a plain git push does not know its destination. This is expected for a newly created local branch.

Verify the destination first

git branch --show-current
git remote -v
git status --short --branch

Confirm both the branch name and remote URL. Then publish the current branch and record the relationship:

git push -u origin HEAD

-u is short for --set-upstream. HEAD selects the current branch, which avoids typing the wrong local name. Git normally creates a remote branch with the same name.

Track an existing remote branch

If the intended remote branch already exists, fetch and create a local tracking branch:

git fetch origin
git switch --track origin/feature/example

For an existing local branch, set the upstream explicitly:

git branch --set-upstream-to=origin/feature/example

Verify the result

git branch -vv
git status --short --branch

The current branch should show its upstream and ahead/behind state. If a hosting provider rejects the push, read the lines above the summary: branch protection or permission errors require a different fix.

Avoid setting push.default globally just to silence one repository’s message. First understand the destination policy. For a compact branch workflow, use the Git branching cheat sheet.
