dst refspec main matches more than one when remote has a main branch and a main tag #8572
Description
Describe the bug
gh pr create fails with error: dst refspec main matches more than one when local and remote repositories have a branch and a tag with the same name. git push --set-upstream origin main succeeds in the same scenario, indicating a potential issue in how gh handles refspecs. gh version: [insert your gh version here].
Steps to reproduce the behavior
- In a local repo, have a branch and a tag named
main. - Ensure the remote (GitHub) repo also has a branch and a tag named
main. - Try creating a PR with
gh pr create --title "Example" -F example.txt. (to an upstream remote, but for this bug report, it doesn't matter if the upstream has the samemainbranch andmaintag conflict) - Observe the error:
error: dst refspec main matches more than one.
Expected vs actual behavior
Expected: gh pr create should handle the branch and tag naming conflict as gracefully as git push, creating the PR without errors.
Actual: The command fails with error: dst refspec main matches more than one.
Logs
Failure:
gh pr create --title "ci: Use GITHUB_OUTPUT envvar instead of set-output command" -F ~/Downloads/prbody.txt
