When you have to update the server

pacman -Syu

Using -Syyu can cause a partial system upgrade if mirrors are out of sync. It leads to higher traffic for mirror owners and it is considered bad practice overall. There are just a few rare cases where it is useful at all.

Forcing anything should always be a conscious decision and never the default.

I’m so lazy I alias “sudo pacman” to “p”

yay -Syyu
