Please do not include screenshots of terminal output in your posts. Instead, copy the terminal output with your mouse, click the </> button in the toolbar of the editor, and paste the output where it is indicated. Screenshots take up room in the database, they are not searchable by the forum’s search engine, and they cannot be copied from.

Be sure to let the entire process finish, no matter how long it takes. Do not interrupt the update process, because you will render your system unbootable.
