If so, then the mirror perhaps isn't already synced, since it just moved from Staging to Testing. You could install it by running sudo pacman -U https://jpn.mirror.pkgbuild.com/testing/os/x86_64/linux{,-headers,-docs}-4.17.9-1-x86_64.pkg.tar.xz but it doesn't solve this issue, see [1]. >It seems, CONFIG_CRYPTO_SALSA20 activates the external API (to be used >by modules and/or applications) while CONFIG_CRYPTO_SALSA20_X86_64 >provides the implementation, so it *should* help (if this is the >stream cipher used by bluez). I don't have knowledge about this. [1] 4.17.8 still in Core allegedly also contains it. $ grep pkg.e.= linux/repos/core-x86_64/PKGBUILD pkgver=4.17.8 pkgrel=1 $ grep SALSA linux/repos/core-x86_64/config CONFIG_CRYPTO_SALSA20=m CONFIG_CRYPTO_SALSA20_X86_64=m I uninstalled $ uname -a Linux archlinux 4.17.9-1-ARCH #1 SMP PREEMPT Sun Jul 22 20:23:36 UTC 2018 x86_64 GNU/Linux from Staging and removed it from the cache and then installed it from Testing and rebooted.
