Hello,
In 12.0.18 MU#57 with plesk-php updates we provided the plesk-php5*-release packages which provide Plesk php yum/apt repositories. It was done in order of making plesk-php for 12.0 compatible with Plesk 12.5 and provides ability to update plesk-php packages via apt/yum without dependency on Plesk updates. The public key will be accessible with one of the nearest updates, please ignore the warnings until the key became available.
