Directly related (10)

rebase in progressGit

fatal: It seems that there is already a rebase-merge directory, and I wonder if you are in the middle of another rebase.

A previous rebase is still in progress (or was interrupted).

untracked files overwrittenGit

error: The following untracked working tree files would be overwritten by checkout/merge

Untracked local files have the same paths as files coming from the other branch.

overwritten by checkoutGit

error: Your local changes to the following files would be overwritten by checkout

Switching branches would discard uncommitted changes in files that differ between branches.

unknown revision HEADGit

fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree.

The repository has no commits yet (or the ref doesn’t exist), so HEAD can’t be resolved.

merge commit revertGit

error: commit x is a merge but no -m option was given.

git revert or cherry-pick on a merge commit needs to know which parent is the mainline.

branch existsGit

fatal: a branch named 'x' already exists

You tried to create a branch whose name is already taken locally.

submodule urlGit

fatal: No url found for submodule path 'x' in .gitmodules

A submodule entry exists in the index but its URL is missing from .gitmodules.

changes overwrittenGit

error: Your local changes to the following files would be overwritten by merge

git pull/merge would modify files you’ve changed but not committed.

LFS smudge errorGit

Error downloading object: x: Smudge error / This repository is over its data quota

Git LFS couldn’t download a large file — missing LFS install, auth problems, or the LFS bandwidth/storage quota is exhausted.

Authentication failedGit

fatal: Authentication failed for 'https://github.com/x/y.git/'

HTTPS authentication to the Git host failed — wrong or expired credentials, or a password used where a token is required.

Two steps away (18)

CONFLICTGit

Git: CONFLICT (content): Merge conflict in file — Automatic merge failed

Both branches changed the same lines; Git needs you to choose the final content before completing the merge/rebase.

index.lock existsGit

fatal: Unable to create '.git/index.lock': File exists. Another git process seems to be running in this repository

A lock file from another (or crashed) Git process blocks this command.

corrupt objectGit

error: object file .git/objects/x is empty / fatal: loose object is corrupt

The local Git object database is corrupted — usually after a crash, disk full or sync tool interference.

cannot lock refGit

error: cannot lock ref 'refs/remotes/origin/x': is at … but expected … / unable to update local ref

Git couldn’t update a reference — stale remote-tracking refs, case-only branch name clashes, or a leftover lock file.

non-fast-forwardGit

Git: ! [rejected] … (fetch first) — error: failed to push some refs

The remote branch has commits you don’t have locally, so Git refuses to overwrite them. Pull (merge or rebase) first, then push.

detached HEADGit

You are in 'detached HEAD' state.

HEAD points at a commit instead of a branch, so new commits won’t belong to any branch.

couldn't find remote refGit

fatal: couldn't find remote ref main

The branch you tried to pull/fetch doesn’t exist on the remote.

not possible to fast-forwardGit

fatal: Not possible to fast-forward, aborting.

pull is configured to fast-forward only, but your branch and the remote have diverged.

not a valid object nameGit

fatal: Not a valid object name: 'main'.

The branch or commit doesn’t exist yet — typically in a new repo before the first commit.

pathspec did not matchGit

error: pathspec 'x' did not match any file(s) known to git

Git couldn’t find the file or branch name you referenced.

src refspecGit

error: src refspec main does not match any

You pushed a branch name that doesn’t exist locally — usually no commits yet, or the branch is called master not main.

no upstream branchGit

fatal: The current branch x has no upstream branch.

The local branch isn’t linked to a remote branch yet, so a bare git push doesn’t know where to go.

Could not resolve hostGit

fatal: unable to access 'https://github.com/…': Could not resolve host: github.com

DNS lookup for the Git host failed from this machine.

unfinished mergeGit

fatal: You have not concluded your merge (MERGE_HEAD exists). Please, commit your changes before you merge.

A merge is still in progress — conflicts were resolved (or not) but not committed.

GH001 large filesGit

remote: error: GH001: Large files detected. File x is 120 MB; this exceeds GitHub's file size limit of 100.00 MB

GitHub rejected the push because a file over 100 MB is in your commits — even if you deleted it later.

publickeyGit

Git: Permission denied (publickey). fatal: Could not read from remote repository.

SSH authentication to GitHub/GitLab/Bitbucket failed — no key, wrong key, or the key isn’t added to your account.

AADSTS700016Azure

Azure AD (Entra ID): AADSTS700016 Application not found in the directory

The client ID in your sign-in request doesn’t exist in the tenant you’re authenticating against.

401HTTP

HTTP 401 Unauthorized

The request has no valid authentication credentials — you need to log in or send a valid token.
