No, wget as listed above does not work, because there is no http://deb.devuan.org/devuan/pool/main/d/devuan-keyring/devuan-keyring_2022.09.04_all.deb, there only is a http://deb.devuan.org/devuan/pool/main/d/devuan-keyring/devuan-keyring-udeb_2022.09.04_all.udeb.
This udeb cannot bei installed with dpkg -i because it would overwrite »/usr/share/keyrings/devuan-archive-keyring.gpg« which is part of packagdevuan-keyring 2017.10.03 .

Solution: download udeb file, purge old devuan keyring, then dpkg -i devuan-keyring-udeb_2022.09.04_all.udeb works.
