systemd: Start request repeated too quickly / service hit its start limit
The service crashed and restarted several times in a short period, so systemd stopped trying (StartLimitBurst).
Job for nginx.service failed because the control process exited with error code
systemd tried to start the service, but its start command failed. The real reason is in the service’s status/journal.
Failed to start x.service: Unit x.service not found
systemd has no unit with that name — the package isn’t installed, the name differs on this distro, or a new unit file wasn’t load…
systemd: Main process exited, code=exited, status=203/EXEC
systemd couldn’t execute the ExecStart command — the path is wrong, the file isn’t executable, or its interpreter is missing.
macOS: Docker Desktop needs privileged access / com.docker.vmnetd could not be started
Docker Desktop couldn't install or start its privileged helper, so it can't set up networking.
macOS: -bash: fork: Resource temporarily unavailable (process limit reached)
The user hit the maximum number of processes (`kern.maxprocperuid`) — usually a fork bomb or runaway child processes.
Homebrew: Error: No available formula with the name "x". Did you mean ...?
Homebrew can't find a formula or cask with that name in the taps it knows.
Homebrew: Error: Your Command Line Tools (CLT) are too outdated. Update them from Software Update / Please update to the latest macOS

A cask install failed because the app is already installed manually (or a leftover exists).
macOS (Apple Silicon): zsh: bad CPU type in executable: ./tool
You ran an Intel (x86_64) program on an Apple Silicon Mac without Rosetta 2 (or an arm64 binary on an Intel Mac).
macOS: Address already in use — Port 5000 is in use by ControlCenter (AirPlay Receiver)
Since macOS Monterey the AirPlay Receiver listens on ports 5000 and 7000, colliding with dev servers like Flask or Docker registr…
macOS: The installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance.
A `.pkg` installation script failed; the Installer UI hides the real reason.
Two steps away (34)
Docker container keeps restarting (Restarting (1) x seconds ago)
The container crashes on start and its restart policy (always/unless-stopped/on-failure) starts it again in a loop.
spec.ports[0].nodePort: Invalid value: 80: provided port is not in the valid range. The range of valid ports is 30000-32767
A NodePort Service asked for a port outside the cluster’s NodePort range (default 30000–32767).
System has not been booted with systemd as init system (PID 1). Can't operate.
You ran systemctl inside an environment without systemd as PID 1 — a Docker container or older WSL.
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
Nginx (or another server) can’t listen on the port because another process already holds it — often Apache, another Nginx, or a s…
Failed to connect to bus: No such file or directory (systemctl --user / timedatectl)
The command needs the D-Bus/systemd bus, which isn’t available in this session — common over su, sudo -u, cron, containers or WSL.
Windows Update error 0x80070422 (service is disabled)
Windows Update (or the Microsoft Store/Defender) can’t run because a required service — usually Windows Update (wuauserv) — is di…
bash: command not found
The shell can’t find an executable with that name in any directory on your PATH.
Context.startForegroundService() did not then call Service.startForeground() / ForegroundServiceStartNotAllowedException
A foreground service didn’t call startForeground() within a few seconds, or the app tried to start one from the background where…
systemd: apache2.service: Main process exited, code=exited, status=1/FAILURE — Job for apache2.service failed because the control process exited with error code
systemd couldn't start Apache — the real error is in the journal or `apachectl configtest`.
exec /docker-entrypoint.sh: no such file or directory (CRLF line endings / missing interpreter)
The entrypoint file exists, but the kernel can’t run it — almost always Windows CRLF line endings in the script, or a shebang poi…
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.
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.
user is not in the sudoers file. This incident will be reported.
Your account isn’t allowed to use sudo.
Too many open files (EMFILE)
The process hit its file-descriptor limit — sockets, files and pipes all count.
OSError: [Errno 98] Address already in use
The port your server wants to bind is already taken by another process.
KeyboardInterrupt (script stopped with Ctrl+C) / ^C traceback
The script was interrupted (Ctrl+C, SIGINT, or a container stop), producing a KeyboardInterrupt traceback.
macOS: zsh: command not found: brew (Homebrew not on PATH on Apple Silicon)
Homebrew is installed in /opt/homebrew on Apple Silicon Macs, which isn’t on PATH until you add its shellenv line.
Homebrew: Error: Permission denied @ dir_s_mkdir - /usr/local/Cellar / /opt/homebrew is not writable
Homebrew can't write to its prefix because the folders are owned by another user or root.
Homebrew: Error: Failure while executing; `git fetch --force origin` exited with 128 / fatal: not in a git directory
`brew update` couldn't fetch the Homebrew repositories — network, a broken git state or safe.directory problems.
gyp: No Xcode or CLT version detected!
node-gyp on macOS can’t find the Xcode Command Line Tools to compile native modules.
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun
The Xcode Command Line Tools are missing or broken — typical right after a macOS update.
macOS: Agreeing to the Xcode/iOS license requires admin privileges, please run "sudo xcodebuild -license" and then retry this command
A new Xcode (or CLT) version needs its license accepted before command-line tools run.
macOS: xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance
A command needs the full Xcode app, but `xcode-select` points to the Command Line Tools only.

Gatekeeper blocked an app that is not notarized by Apple.

zsh: compinit: insecure directories, run compaudit for list. Ignore insecure directories and continue [y] or abort compinit [n]?
zsh refuses to load completions from directories owned by another user or writable by others.
zsh: no matches found: package[extra] (glob pattern not matched)
zsh treats `[ ]`, `*` or `?` in an argument as a glob and fails when nothing matches, unlike bash which passes the text through.
Docker: Bind for 0.0.0.0:80 failed: port is already allocated
Another container or host process already publishes that host port.
driver failed programming external connectivity on endpoint: iptables: No chain/target/match by that name
Docker’s iptables rules were wiped (firewalld/ufw reload, iptables flush) while Docker was running, so it can’t publish ports.
Go: listen tcp :8080: bind: address already in use
The port your Go server wants is already taken by another process (or a previous instance of your app).
macOS: hdiutil: attach failed - image not recognized / no mountable file systems
The `.dmg` file is corrupted, incomplete, or not actually a disk image (often an HTML download page).
macOS: There is not enough available storage to install this update / Installation of macOS could not continue
Software Update needs several GB of free space (often 25-35 GB) to download and stage the update.
