Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
The docker CLI can’t talk to the Docker engine — it isn’t running, or your user can’t access the socket.
exec /entrypoint.sh: permission denied (container won't start)
The entrypoint or command isn’t marked executable inside the image, or it’s on a volume mounted noexec.
Permission denied writing to a mounted volume inside a Docker container
The process inside the container runs as a user (UID) that doesn’t own the bind-mounted host folder, so reads/writes fail with EA…
SELinux is preventing ... / avc: denied { read } for pid=... (permission denied despite correct permissions)
SELinux blocked the access — file permissions look fine, but the file’s security context or a boolean doesn’t allow the service t…
npm ERR! code EACCES — permission denied
npm can’t write to a directory — usually global installs into a root-owned folder.
PermissionError: [Errno 13] Permission denied: '/path'
The OS refused the file operation — no permission, a directory passed to open(), or (on Windows) the file is open elsewhere.
WARNING: UNPROTECTED PRIVATE KEY FILE! Permissions 0644 for 'key.pem' are too open
SSH refuses to use a private key that other users can read; it must be readable only by you (chmod 600).

java.nio.file.AccessDeniedException: /path
The OS denied a file operation to the Java process.
NotAllowedError: Failed to execute 'writeText' on 'Clipboard': Document is not focused.

The shell can’t find an executable with that name in any directory on your PATH.
OCI runtime create failed: exec: "x": executable file not found in $PATH
The command you asked the container to run doesn’t exist inside the image — wrong command name, a shell that isn’t installed (bas…

Windows refused an operation because the account or process lacks permission — seen in Windows Update, installers, Task Scheduler…

Node isn’t allowed to bind that port — ports below 1024 need root on Linux/macOS, and some Windows ports are reserved.
Error: EPERM: operation not permitted, rename / unlink
The OS refused a file operation — on Windows usually because another process (antivirus, editor, indexer) has the file locked.

Error: Could not load the "sharp" module using the linux-x64 runtime
sharp’s native binary for this OS/CPU isn’t installed — usually node_modules installed on another platform (Mac → Linux/Docker).
You installed esbuild for another platform than the one you're currently using.
node_modules contains esbuild’s binary for a different OS/CPU.
Error: /app/node_modules/bcrypt/lib/binding/bcrypt_lib.node: invalid ELF header
