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.

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.

cannot rebaseGit

error: cannot pull with rebase: You have unstaged changes. Please commit or stash them.

A rebase (or pull --rebase) needs a clean working tree.

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.

gc warningGit

warning: There are too many unreachable loose objects; run 'git prune' to remove them.

Git’s automatic garbage collection found many unreachable objects and is asking you to prune.

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.

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.

Two steps away (15)

126 incorrect key fileMySQL

MySQL ERROR 126 (HY000): Incorrect key file for table; try to repair it

MySQL can’t use a table’s index file — usually a full tmp disk during a query, or MyISAM corruption.

malformed databaseSQL

sqlite3.DatabaseError: database disk image is malformed

The SQLite file is corrupted.

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.

unrelated historiesGit

Git: fatal: refusing to merge unrelated histories

The two branches have no common ancestor — typically a local repo and a remote that were both initialized separately.

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.

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.

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.

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.

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.

503HTTP

HTTP 503 Service Unavailable

The server is temporarily unable to handle the request — overloaded, in maintenance, or has no healthy backends.

Maintenance modeWordPress

WordPress: Briefly unavailable for scheduled maintenance. Check back in a minute.

An update was interrupted and WordPress left its `.maintenance` file behind, so the site stays in maintenance mode.

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.

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.

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.

branch existsGit

fatal: a branch named 'x' already exists

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