What does this mean in Zorin OS 18.1?

Hi!

In Terminal I was doing:
sudo apt update &&s sudo apt upgrade

Then at the end I got:
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
All packages are up to date.
s: command not found

What does this mean:

s: command not found

Any help wold be greatly appreciated.

Hey I just found the answer, it was a typo.

sudo apt update &&s sudo apt upgrade

The: S

The correct command is:

sudo apt update && sudo apt upgrade

My mistake, sorry!
