Upgrading/Updating using Pacman

[Ptab2newb]

now there is some wrong information.

Thx for this zerabeta - i'll run these accordingly!

Code:

# updates package lists, does not update anything
$ sudo pacman -Sy
# like previous but deeper, it's needed if local cache is messed up somehow
$ sudo pacman -Syy
# updates the system, however updating package lists are needed
$ sudo pacman -Su
# updates package lists and updates the system
$ sudo pacman -Syu

pacman does not update other package systems, like flatpak, snap and others.

"pamac" can access AUR if that has been used.

Still hoping for some guidance on display control, including screen brightness and font sizes!
