[aur-general] Install fails on x86_64

[set]

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.
