I just installed arch linux on my raspberry pi and after booting first time I connected it with ethernet to my router and runned the command:
$this->bbcode_second_pass_code('', 'pacman-key init')
which worked just fine then i typed:
$this->bbcode_second_pass_code('', 'pacman -Syu')
and everything worked just fine until the end where it just said
$this->bbcode_second_pass_code('', 'error: iana-etc: signature from "Arch Linux ARM Build System <builder@archlinuxarm.org>" is unknown trust
: : File /var/cache/pacman/pkg/iana-etc-20200428-1-any.pkg.tar.xz is corrupted (invalid or corrupted package (PGP signature)).
Do you want to delete it? [Y/n] ')
for all packages and then after I had deleted them all it just ended the process by saying no packages were upgraded. I tried reinstalling Arch Linux ARM and I even re-downloaded Arch Linux ARM, but I just received the same error. <
Does anyone know how I can fix it?
