сделал так:
# cp /etc/cups/cupsd.conf.default /etc/cups/cupsd.conf
заработало. Взято отсюда:

После обновления dhcpcd с 5.5.4 на 5.5.5(6) пропал инет (beeline VPN). Сетевуха RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06).
После отката до 5.5.4 сеть восстанавливается. Кто-нибудь в курсе?
Была та же проблема после штатного обновления. Выполнил:
pacman -S gnome gnome-extra
Доустановились некоторые зависимости, всё заработало.

Не нужно!
hal и fam в DAEMONS rc.conf прописаны?
Из репозитория пропал totem-xine. Случилось это, примерно, одновременно с появлением ядра 2.26.30. При этом pacman предложил заменить пакет totem-xine на обычный totem. Кто знает в чём причина?
PKGBUILD`ы для codecs и codecs-extra появились в AUR
Пакет codecs удалён из репозитория extra по лицензионным соображениям. Этот пакет включал в себя различные не свободные кодеки, такие как QuickTime, кодеки windows (wma, wmv) и другие.
Можно использовать аналогичный пакет codecs-all из репозитория archlinuxfr:
