It seems can't push commits to a new branch to a mirror repository without setting push to upstream. I created a mirror repository in gitea, it synchronizes from a GitHub repository period. I cloned the gitea repository to my local and created a new branch. Now I want to push the new branch to gitea, it reports that the remote repository is read-only. "remote: mirror repository is read-only" Does it mean that it can't push to a mirrored repository and the only way is to convert the repository to a normal one?
