The new SAMBA+ 4.12.7 packages do also address the following issue:

The sernet-samba rpm packages are signed with SerNet's gpg build key to guarantee authenticity. If you have installed the sernet-build-key-1.4-8 key package, the verification might fail due to an rpm issue. After installing the new version sernet-build-key-1.4-9, the issue needs to be fixed manually.

If you are affected, please first remove the SerNet Samba keys from the rpm keyring with the following command:
# rpm --allmatches -e gpg-pubkey-f4428b1a
# rpm --allmatches -e gpg-pubkey-1b6d0337

Afterwards use the following command to import the key into the rpm keyring:
# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-SerNet-Samba-Team-F4428B1A \
