Errors when running `pacstrap`

### (PGP)Key "..." could not be imported

`error: linux-api-headers: key "F990EB20FAEsomhing" is unknown`

    Import PGP key EAE999BD, "Allan McRae <me@allanmcrae.com>", created on 2011-06-03? [Y/n]

error: key "Allan McRae <me@allanmcrae.com>" could not be imported

Can be due to incorrect date, to fix set the time manually or use `ntpd -qg` to use the network to set the time.(a case)

### Key import fails otherwise

One solution is to change the core repo in `/etc/pacman.conf` from `SigLevel = PackageRequired` to `SigLevel = Optional TrustAll` But that would decrease security by a lot.
