It was really worth waiting for a week more, the harvest was abundant today: 334 packages (1.42 GIB).
On Budgie Desktop, the update (on the Software Center graphic application) remained blocked at the end on the message "Updating Solus Restitory". So I left the application, then I relaunched it, it replied "Software is update". As a precaution, I rebooted my computer and everything has been fine so far.
Thank you for the hard work of the Solus developer team to give us a quality Linux distribution that we could hardly do without today.
Cheers!
