After upgrading to `openssh-9.8p1`, the existing SSH daemon will be unable to accept new connections (see <https://gitlab.archlinux.org/archlinux/packaging/packages/openssh/-/issues/5>). When upgrading remote hosts, please make sure to restart the sshd service using `systemctl try-restart sshd` right after upgrading.
We are evaluating the possibility to automatically apply a restart of the sshd service on upgrade in a future release of the openssh-9.8p1 package. URL: https://archlinux.org/news/the-sshd-service-needs-to-be-restarted-after-upgrading-to-openssh-98p1/
