[SOLVED] Invalid signature while updating.

I'm trying to update a machine rarely used (last time was about 6 months ago)
After having downloaded about 1Gb of packages,
Pacman shows the following message: (my translation from Italian)

checking package integrity
error: linu-api-headers: the signature "Frederik Schwan <frederik.schwan@linux.com"> has an unknown reliability
the file /var/cache/pacman/pkg/linux-api-headers-6.18-1-x86_64.pkg.tar.zst is corrupted
(the package is not valid or is corrupted(PGP signature)).
Do you want to delete it ?

(I reply "n")

same errors on glibc2, gcc-libs, libntgcp2-1, libseccomp, binutils, libtool, ncdu
after those errors, I get the following message:

errors occurred, no packages were updated

and the program terminates.
What can I do ?

Thank you very much.
Updating the archlinux-keyring package solved my problem.

Re: [SOLVED] Invalid signature while updating.

I have problems updating keys on archlinux machines. Can someone suggest a solution?
I'm following the steps to reset the keys

sudo pacman-key --init
sudo pacman-key --populate
sudo pacman -Sy archlinux-keyring
sudo pacman-key --refresh-keys

In all cases, when performing the last step, it stops recording.:

gpg: Receiving error 'atsutane@freethoughts.de ' via WKD: A common mistake
gpg: error reading key: A common error
gpg: Receiving error 'atsutane@freethoughts.de ' via WKD: A common mistake
gpg: error reading key: A common error

Re: [SOLVED] Invalid signature while updating.

I solved the problem  with the command:

pacman -Sy --needed archlinux-keyring && pacman -Su

as suggested in the page:

That last step isn't necessary.

For the problem we need actual errors. https://bbs.archlinux.org/viewtopic.php?id=57855
