Issue Plesk Update: WARNING: The following packages cannot be authenticated! apache2-mpm-prefork apache

[MarkusG]

Hello,

I'm running Plesk 17.5.3 on Debian 8.10, last Update was #70. The latest Update/Upgrade failed with this error message:

WARNING: The following packages cannot be authenticated!
apache2-mpm-prefork apache2-mpm-event apache2 apache2-bin apache2-data

I've tried "Repair the failed Upgrade/Installation"-Link in the Error-Message. After that, everything seemed fine, but today the same error message appears.

Any hints on this one?

Thanks and regards, Markus
