Or
dnf install distribution-gpg-keys
rpm --import /usr/share/distribution-gpg-keys/remi/RPM-GPG-KEY-remi2017
I switched out the key in the file /etc/pki/rpm-gpg/RPM-GPG-KEY-livna with the one you provided and it worked like a charm. Thank you very much, remi!!! I'll be marking this thread as solved, then.
