fatal: bad revisionfatal: bad revision
The specified revision (commit hash, branch name, tag) does not exist.
fatal: Not possible to fast-forward, abortingA pull with --ff-only failed because the branches have diverged.
You configured git pull to only allow fast-forward merges (--ff-only), but your local branch has commits that are not on the remote, making a fast-forward impossible.
Use git pull --rebase to rebase your commits on top of the remote. Or use git pull without --ff-only to create a merge commit. Or git fetch first, then decide how to integrate the changes.
fatal: bad revisionThe specified revision (commit hash, branch name, tag) does not exist.
You are in 'detached HEAD' stateHEAD is pointing to a specific commit rather than a branch, meaning new commits will be orphaned.
fatal: refusing to merge unrelated historiesGit refuses to merge two branches that do not share a common ancestor.
fatal: 'origin' does not appear to be a git repositoryGit could not connect to the specified remote repository.
fatal: not a git repositoryThe current directory is not inside a Git repository.
error: non-fast-forward updateThe push would rewrite history on the remote branch and is rejected.
