Hello,
I have just issued the following command in two RPI4 systems:
# pacman -Syyuu
and I have got:
error: iwd: signature from "Arch Linux ARM Build System <builder@archlinuxarm.org>" is invalid
:: File /var/cache/pacman/pkg/iwd-1.27-1-aarch64.pkg.tar.xz is corrupted (invalid or corrupted package (PGP signature)).
Do you want to delete it? [Y/n]
after choosing to keep this file:
Do you want to delete it? [Y/n] n
error: failed to commit transaction (invalid or corrupted package)
Errors occurred, no packages were upgraded.
same result if I delete it
