Black screen | Failed to start Snap Daemon

Hello, thank you for your time and interest :slight_smile:

Now it works, but I think I have an issue.

I have transferred all my personal data (Documents, video...) on my External drive.

I note that the system takes now... 230 GB out of 250 GB !!! Is it normal?

I have had some troubles with recent updates.
I wonder if this update has duplicated some system data!

I am considering to reinstall my system :).

Have a nice day.

José, France
