Best answer

Within Emacs, list all packages by

M-x list-packages

and it will automatically refresh the archive contents.

Then, press U to mark all upgradable packages to be upgraded.

Last, press x to perform the new updates.

Emacs will then download and install all upgradable packages. It will also ask you whether to delete the old packages.
