Same problem if I try to downgrade readline and bash

Use pacman -U to downgrade readline+bash from your cache (this skips signature verification by default). You may even have to log out and in again. If you are paranoid, verify both packages with pacman-key -v before installing them (I think that one should still work, as opposed to pacman+gpgme).

Wouldn't it be great if I could check the file checksum of bash at https://www.archlinux.org/packages/core/x86_64/bash/?

Can you at least confirm the checksums to be the same on your machine?

Looks good to me: sha256sum /var/cache/pacman/pkg/bash-4.3-3-x86_64.pkg.tar.xz c02d4486ffd345b83868afa5f8ff61ac720e96559ac1b8bb84051625401364c0 sha256sum /var/cache/pacman/pkg/readline-6.3-3-x86_64.pkg.tar.xz fc31861827cc94578ae69158312e605d2ffb26f1658e47406659f75f2bcc7196 Cheers, ushi
