Like Parsa Mousavi said, it looks like you don't have administrator privileges. Try running it on the default user you created while installing (if you are not on it already) and use
sudo apt update && sudo apt upgrade
I'm guessing you did
apt update instead of
sudo apt update.
If a command outputs
Permission Denied, try adding
sudo before it.
