[aur-general] Install fails on x86_64

Hello, Fresh install fails on x86_64 with cracklib integrity verification failure and signer verification failure. Tried with 12.12 and 13.01 install images. Other signature failures occur with vim packages. pacman-key --populate and --update result in 'No need to update/refresh'. Can't report the relevant keys as I can't access the machine at any time. arch-chroot /mnt drops in an irresponsive shell. Even ls fails in this chroot. Used mirror.archlinux.ikoula.com . Any hints how to resolve this ? Thanks.
