which keyring to install to access jessie archive?

[Harald Dunkel <harald.dunkel@aixigo.com>]

Hi folks,

apparently the jessie archive repository is still alive, but if I try to
update the package list there is an error message

	W: GPG error: http://archive.debian.org/debian jessie Release: The
	following signatures couldn't be verified because the public key is
	not available: NO_PUBKEY 8B48AD6246925553 NO_PUBKEY 7638D0442B90D010
	NO_PUBKEY CBF8D6FD518E17E1

I tried installing

	debian-archive-keyring_2017.5~deb8u1_all.deb
	debian-archive-keyring_2019.1+deb10u1_all.deb
	debian-archive-keyring_2021.1.1+deb11u1_all.deb
	debian-archive-keyring_2023.4_all.deb

but neither provides the missing keys.

Which debian keyring packages do I have to install to verify Debian
packages from the archive repositories?


Regards
