Two steps away (13)

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.

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.

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.

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.

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.

divergent branchesGit

hint: You have divergent branches and need to specify how to reconcile them.

Git 2.27+ asks you to choose merge, rebase or fast-forward-only when local and remote both have new commits.

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.

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.

branch existsGit

fatal: a branch named 'x' already exists

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