What was the result of the apt update and upgrade? Were there any errors when you updated?
And it appears you're having two different issues on two different machines.. Is the Asus Vivobook S533 in your first post still affected?
Is another issue - I would create another thread with that machine and issues; just to keep things neat. I see this thread is marked as Solved
.
Check this thread out for common issues related to Software Center - blank installed screen is one of the listed issues.
