Git push -f after rebase modified 2 branches

Question

I have made a simple git fetch --all --prune to fetch modifications from master then I did git pull .

After that I went back on another branche to rebase it from master with git rebase master . After this everything seem work.

But went I did git push -f to send this modification on distant Gitlab, git pushed on my rebase branch and on another branch that I don't even touch since a week. This is the first time git do that.

There is the git traces

Do you have same clues about this weird thing ? Did I miss/fail something

Answer 1

Check your push.default setting . I'd say the rule of thumb is: if you push something (especially using --force ) always specify the remote and branch
