Sorry for the noobish question but recently when I try pacman -Syu I get:
$this->bbcode_second_pass_code('', ':: Synchronizing package databases...
core is up to date
warning: resuming download of extra.db not possible; starting over

error: could not open file /var/lib/pacman/sync/extra.db: Failed to open '/var/lib/pacman/sync/extra.db'

')
I tried pacman-db-upgrade and pacman -Syy but they didn't help..
What have I done this time?!
