I noticed that I didn’t get any updates in last few days. Even when plasma 5.13 released it showed no updates that’s how I got to know something isn’t right.

I ran

sudo pacman-key --init; sudo pacman-key --populate archlinux antergos; sudo pacman-key --refresh-keys; sudo pacman -Syyuu

from - https://forum.antergos.com/topic/8197/there-are-not-updates/3

After that also pacman shows no updates but pamac shows about 200+ updates
