Ошибка не найдена цель linux zen

Several times I updated pacman -Syy , pacman -Syu and some other commands.
I have multilib source uncommented in pacman.conf.
My last thoughts were about pacman-key, I was trying to change keyserver in /etc/pacman.d/gnupg/gnu.conf, run pacman-key --refresh-keys and pacman-key --populate archlinux but it didn’t help me. Was googling a lot, but I guess I need to ask here.
pacman -S xorg works, but pacman -S yaourt and several others not

UPD: pacman.conf

Trying to install

 sudo pacman -S light 
 error: target not found: light 
 sudo pacman -S alsamixer
 error: target not found: alsamixer   

У меня было много проблем с pacman в моей новой системе Arch. Я не могу ничего установить.

[root @ life ~] # pacman -S pacaur

ошибка: цель не найдена: pacaur

Я перепробовал все, включая pacman -Syyu, переустановку pacman и переписку с mirrorlist, что наводит меня на мысль, что это может быть проблема с mirrorlist или pacman.conf

Может кто-нибудь помочь?
