  • Administrative Privileges: You’ll likely need administrative rights (e.g., sudo on Linux/MacOS or running PowerShell as Administrator) to install or update system-wide.
  • Alternative Update Methods:
    • Windows: If you installed using the MSI installer, you might need to download and re-run the latest installer to get updates.
    • Linux: Some package managers (like apt) might offer update mechanisms (sudo apt install --only-upgrade awscli).
  • Shell Restart: After updating, it’s a good practice to restart your terminal or command prompt.
