signature from "David Macek <david.macek.0@gmail.com>" is unknown trust

Hi All.

Today I was not been able to update my MSYS2 instance. After pacman -Suy command I got the following questions for many packages:

error: autoconf: signature from "David Macek <david.macek.0@gmail.com>" is unknown trust
:: File /var/cache/pacman/pkg/autoconf-2.71-1-any.pkg.tar.zst is corrupted (invalid or corrupted package (PGP signature)).
Do you want to delete it? [Y/n]
error: autoconf2.13: signature from "David Macek <david.macek.0@gmail.com>" is unknown trust
:: File /var/cache/pacman/pkg/autoconf2.13-2.13-3-any.pkg.tar.zst is corrupted (invalid or corrupted package (PGP signature)).
Do you want to delete it? [Y/n]

This case is very similar to #2343 and #2033.

Thank you!

Wanted to throw my hat in to note this still appears to be happening.

This was usually when the package key expired and wasn't refreshed soon enough (or it was forgotten to be re-newed by the maintainer).
