Hi, I just installed ZorinOS 16 on my PC and tried using the Software Updater and after a few seconds got this error

Does anyone know how to fix this?
Thanks

Let's check a verbose printout of what the updater is saying.
Can you open a terminal with ctrl+alt+t
Enter in

sudo apt update

relay the output here.
