All Errors

The 'two-factor authentication is required' error occurs when your Docker Hub account has 2FA enabled, but you're trying to log in with your password instead of a Personal Access Token (PAT). Docker Hub requires access tokens for CLI authentication when two-factor authentication is active.

This error occurs when Docker encounters an unrecognized command or malformed syntax in your Dockerfile. Common causes include file encoding issues, missing RUN prefixes, incorrect line continuations, or Windows line endings (CRLF vs LF).

The 'unable to delete image - image is being used by stopped container' error occurs when you try to remove a Docker image that still has one or more stopped containers associated with it. Remove the stopped containers first, or use the force flag to delete the image anyway.

This Python error occurred during execution. Check the error message for details on what went wrong and follow the steps below to diagnose and fix the issue.

The 'No such container' error occurs when Docker cannot find a container you're trying to interact with. This typically happens when using an incorrect container name or ID, or when the container has already been removed.

This error occurs when a Git branch reference file becomes corrupted, typically due to a system crash, power failure, or disk error. The fix involves deleting the corrupted ref file and recovering from the reflog or remote.

This error occurs when you try to create or start a Docker container with a name that's already taken by an existing container. Even stopped containers keep their names until removed.

Docker exit code 125 occurs when the docker run command itself fails before the container can start. This typically indicates a problem with the Docker daemon, invalid command syntax, or system resource conflicts.

The WORKDIR error occurs when Docker cannot change to the specified directory during a container run or build. This typically happens with multi-stage builds, incorrect base images, or when running containers with a WORKDIR that was not created. Verify your Dockerfile structure or use absolute paths.

Exit code 127 indicates that a command specified in your Docker container could not be found. This is a standard Linux/Unix shell error code meaning the shell cannot locate the executable you're trying to run.

This error occurs when a Docker container tries to execute a script or command that requires Python, but the Python interpreter is not installed or is at a different path in the container's filesystem.

DNS timeout errors occur when Node.js cannot resolve a hostname within the expected timeframe, often due to network issues, slow DNS servers, or threadpool exhaustion. This guide shows how to configure timeouts and implement caching strategies.

Exit code 139 occurs when a Docker container receives SIGSEGV (signal 11), indicating a segmentation fault caused by invalid memory access. This typically results from application bugs, library incompatibilities, or hardware issues requiring debugging and code analysis to resolve.

This error occurs when Docker cannot parse the volume mount syntax in your docker run command or docker-compose.yml. Common causes include missing colons, relative paths, unset environment variables, or incorrect path formatting on Windows.

The 'Version in docker-compose.yml is unsupported' error occurs when your Docker Compose file specifies a version number that your installed docker-compose tool doesn't recognize. This is typically resolved by upgrading Docker Compose, removing the version field entirely (for Compose V2), or lowering the version number.

The SQLITE_IOERR_UNLOCK error occurs when SQLite cannot properly release a file lock during database operations. This is an I/O error that typically indicates file system permission issues, disk space problems, or conflicts with antivirus software. The error prevents proper transaction completion and can lead to database corruption if not resolved.
