Version 2022.12 of package Gnu-Elpa-Keyring-Update has just been released in GNU ELPA. You can now find it in M-x list-packages RET.
Gnu-Elpa-Keyring-Update describes itself as: ======================================= Update Emacs's GPG keyring for GNU ELPA ======================================= More at https://elpa.gnu.org/packages/gnu-elpa-keyring-update.html ## Summary: This package updates the GPG keys used by the ELPA package manager (a.k.a `package.el') to verify authenticity of packages downloaded from the GNU ELPA archive. Those keys have a limited validity in time (for example, the first key was valid until Sep 2019 only), so you need to install and keep this package up to date to make sure signature verification does not spuriously fail when installing packages. ## Recent NEWS: [Not available 🙁]
