Signing key has expired for Emacs for windows zip archive (?)

["ISHIKAWA,chiaki" <ishikawa@yk.rim.or.jp>]

Hi,

I tried to download Emacs for Windows, based on the description of
https://www.gnu.org/software/emacs/documentation.html

Unfortunately, it seems that the signing key for the zip archive either 
has expired (or revoked?)
or worse some serious issue might have crept in.

The desription:


      Windows

GNU Emacs for Windows can be downloaded from a nearby GNU mirror 
<http://ftpmirror.gnu.org/emacs/windows>; or the main GNU FTP server 
<http://ftp.gnu.org/gnu/emacs/windows/>.
Unzip the zip file preserving the directory structure, and run 
|bin\runemacs.exe|. Alternatively, create a desktop shortcut to 
|bin\runemacs.exe|, and start Emacs by double-clicking on that 
shortcut's icon.

The Windows binaries are signed by Phillip Lord |8E64 B119 FE4B AC58 
C767 D5EC E095 C1A6 3FB1 EAD2|.


Well, I got the following error when I tried to verify the integrity of 
the archive.

I could not figure out how to change the gpg's output changed into 
English, but
it says the key was revoked by the owner.

I am not sure what is going on, and could not resolve the issue after 
trying to update the key, etc.
Note that the "8E64 B119 ..." is different from the GPG's message. It is 
possible that the old archive signed in August was
signed with a different key, but somehow when I looked around "I got 
this "8493 0FFB ..." fingerprint.

I think whoever maintains the archive ought to be aware of the issue.

TIA
