[ERROR] Couldn't add GPG key for Flair repository

I am trying to install FLUKA on Windows11, following the introduction

Installing FLUKA.CERN and Flair on Windows using WSL | The official CERN FLUKA website

While acting the step3.1, there is the error as the topic title, which seems there is the same problem as link:

Windows 10 Ubuntu Error: Couldn’t add GPG key for Flair repository - Installation - FLUKA User Forum

I tried the two methods inside the link above, but still didn’t work, the error out file as attached.

Could anybody give me some suggestions?

Thanks, in advance.

Dear Zhongjian,
