Hallo hal,

there was a broken devuan-keyring package in the repository for a
couple of hours - everyone who installed it got locked out from the
repo as it failed to pass the keys to apt's keyring. See this issue:
https://git.devuan.org/devuan-packages/devuan-keyring/issues/15

Or just run

$ gpg --keyring /usr/share/keyrings/devuan-keyring.gpg --export \
94532124541922FB | apt-key add -

to give apt access to the repository (and the fixed devuan-keyring
package) again.

libre Grüße,

Florian
