Thanks, Micah. I got the key added but it fails with the same error.

That suggests that the GPG key was already imported, hmm...
I thought I had success with the key the first time but got the keyring error.
You can always try removing/adding the remote again:
$ sudo ostree remote delete fedora-workstation
$ sudo ostree remote add fedora-workstation
https://dl.fedoraproject.org/atomic/repo/
$ sudo ostree remote gpg-import fedora-workstation -k
/etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-29-primary
Imported 1 GPG key to remote "fedora-workstation"
$ rpm-ostree rebase fedora/29/x86_64/silverblue
