Several errors after fresh install of Zorin OS 17 Core

Can you please launch Software & Updates and in the "Download from" drop down menu, ensure you are set to Main Server.
Once this is done, close Software & Updates and let it refresh when it asks.
Launch terminal and run

sudo apt update && sudo apt full-upgrade

Once you have done these, please check your Manufacturer page to see if your Make and Model has a BIOS Firmware Update available for that machine.
