PGP signature error when installing 7zip-25.01-1 — missing key[SOLVED]

When i tried update with command:
sudo pacman -Syu
I get this error:
error: 7zip: signature from "T.J. Townsend <blakkheim@archlinux.org>" is invalid
:: File /var/cache/pacman/pkg/7zip-25.01-1-x86_64.pkg.tar.zst is corrupted (invalid or corrupted package (PGP signature)).
Do you want to delete it? [Y/n] y
error: failed to commit transaction (invalid or corrupted package)
Errors occurred, no packages were upgraded.

What i tried:
1) sudo pacman -Scc
     sudo pacman -Syyu

2) sudo pacman -Sy archlinux-keyring
     sudo pacman-key --populate archlinux
     sudo pacman -Syu

3) sudo rm -rf /etc/pacman.d/gnupg
     sudo pacman-key --init
     sudo pacman-key --populate archlinux
     sudo pacman -S archlinux-keyring
     sudo pacman -Syu

4) sudo pacman-key --keyserver hkps://keyserver.ubuntu.com --recv-keys 9F4D2C6A
#gpg: keyserver receive failed: No data
#==> ERROR: Remote key not fetched correctly from keyserver.

5) sudo pacman-key --keyserver hkps://pgp.mit.edu --recv-keys 9F4D2C6A
#gpg: keyserver receive failed: No data
#==> ERROR: Remote key not fetched correctly from keyserver.

6) curl -s https://keyserver.ubuntu.com/pks/lookup … 0x9F4D2C6A | gpg --import
#gpg: no valid OpenPGP data found.
#gpg: Total number processed: 0

7) sudo pacman-key --keyserver hkps://keyserver.ubuntu.com --refresh-keys

8) sudo pacman-key --init
     sudo pacman-key --populate archlinux
     sudo pacman-key --refresh-keys

9) sudo pacman -Sc

10)sudo rm /var/cache/pacman/pkg/7zip-25.01-1-x86_64.pkg.tar.zst
#rm: cannot remove '/var/cache/pacman/pkg/7zip-25.01-1-x86_64.pkg.tar.zst': No such file or directory
      sudo pacman-key --init
      sudo pacman-key --populate archlinux
      sudo pacman-key --refresh-keys
      sudo pacman -S 7zip

11) I tried all it with and without vpn.

Questions:

1) Is this key (9F4D2C6A) missing from the official Arch keyring?

2) Is there an alternative trusted source for this key?

3) Could this be an issue with the 7zip package signature in the repository?

P. S.  : Sorry if something looks strange — this is my first message on the Arch Forum

The error is that the sig is invalid, not that it's missing. First, try using a different mirror.

signature also shows up as unknown trust in https://bbs.archlinux.org/viewtopic.php?id=307575 (albeit misspelled, so pot. free interpretation of the error - we'll see)

reflector --country "Netherlands" --latest 10 --sort rate --save /etc/pacman.d/mirrorlist

Also add these two server to mirrirlist:
Server = https://mirror.koddos.net/archlinux/$repo/os/$arch
Server = https://mirror.i3d.net/pub/archlinux/$repo/os/$arch

Problem solved.

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

(you'll probably have to shorten the subject a bit)
