User aborted workflow.

Error message

User aborted workflow.

What it means

Raised at the end of the trust-key workflow when the operator declines the final 'Really trust this key?' confirmation. phutil_console_confirm() returned false (answer 'n' or no readable 'y' from stdin), so the workflow converts the decline into a PhutilArgumentUsageException and exits without changing the key: setIsTrusted(1) and save() are never reached.

Solutions

1. If you intended to trust the key, re-run the command and answer 'y' at the prompt.
2. When automating, supply the confirmation explicitly: printf 'y\n' | ./bin/almanac trust-key --id N (or yes | ...), knowing this trusts the key unattended.
3. If you declined deliberately, nothing is broken: the key's isTrusted flag is unchanged; verify in the UI if unsure.

try {
  // invoke trust-key workflow
} catch (PhutilArgumentUsageException $ex) {
  if ($ex->getMessage() === pht('User aborted workflow.')) {
    // Deliberate decline: exit cleanly, key untouched.
    exit(0);
  }
  throw $ex;
}

When it happens

Trigger: Executing ./bin/almanac trust-key --id N interactively and answering 'n'; or running it non-interactively (cron, piped stdin, no TTY) where the confirm prompt gets EOF instead of 'y'.

Common situations: Automating trust-key in a deploy script without feeding stdin; operator hesitating at the red 'bypass policy and security checks' warning; CI jobs or SSH sessions without an interactive terminal.
