Hello everybody,

I have a new Linux server with current Plesk license:

Version Plesk Onyx v17.8.11_build1708180613.11 os_Ubuntu 18.04
OS Ubuntu 18.04.1 LTS

and during the automatic update the following error message appears regularly and the package cannot be loaded:

Fehler: Paketliste konnte nicht abgerufen werden: 2019-02-12 12:12:10 INFO: pum is called with arguments: [--list, --repo-info, --json] 2019-02-12 12:12:11 ERROR: W:GPG error: Index of /imunify360/ubuntu/16.04 xenial InRelease: The following signatures couldnt be verified because the public key is not available: NO_PUBKEY 8C55A6628608CB71, E:The repository Index of /imunify360/ubuntu/16.04 xenial InRelease is not signed. 2019-02-12 12:12:11 ERROR: Exited with returncode 1.

I connect to the server via SSH and run :

#plesk bin license --retrieve

the message:
