Certificates untrusted on fresh install

Feedback

For testing, I just installed a copy of Zorin OS 16 Core - bare metal.
After logging in, I opened terminal and ran sudo apt update (as this is the first thing all users should do immediately after installing Zorin OS).
I was greeted with

I ran sudo apt install --reinstall ca-certificates which cleared that up.

But this may affect many users and they may not know what to do.

It may be because the build .iso I used was Zorin OS 16.1
