When I enter this command PacMan -Syu I get this message “nothing to do”
you are all up to date = nothing to update
There’s nothing to do because… There’s nothing to update to. You’re up to date.
Is there reason why you think there’s a problem?
If you believe you haven’t installed the update that was release on 2020-08-16 then you may want to try updating your mirrors.
sudo pacman-mirrors --fasttrack
then you can do you’re
sudo pacman -Syyu
(you can also limit the number of mirrors by using sudo pacman-mirrors --fasttrack 5
) This would limit the number of mirrors to 5
