GPG Bad Signature for ARMv8 Raspberry Pi 3/4

[mijik]

When I downloaded http://os.archlinuxarm.org/os/ArchLinux ... est.tar.gz and http://os.archlinuxarm.org/os/ArchLinux ... tar.gz.sig and tried to verify the download, GPG shows the following error:

Command:
$this->bbcode_second_pass_code('', '
gpg --verify ArchLinuxARM-rpi-aarch64-latest.tar.gz.sig
')

Output:
$this->bbcode_second_pass_code('', '

I imported the key with the following command:
