BThe session <code>dev</code> does not exist.
CYou need to create a new session first.
DThe tmux server is not installed.

    Being already attached or needing to create a session are not causes of this error; installation issues would give different errors.

  3. Final Answer:

    The session dev does not exist. -> Option B

  4. Quick Check:

    Attach error 'no sessions' = session missing [OK]
Quick Trick: Check session list with 'tmux ls' before attaching [OK]

  • Assuming session exists but is attached
  • Thinking tmux is not installed
  • Ignoring session name typos
