On my debian VPS, I tried to restart my elasticsearch but it failed.  
I have no trace on /var/log/elasticsearch.log.  
I tried also to update my elasticsearch cluster but I received the following (sorry this is in french):  
Erreur de GPG : [https://packages.elastic.co](https://packages.elastic.co) stable Release : Les signatures suivantes n'ont pas pu être vérifiées car la clé publique n'est pas disponible : NO\_PUBKEY D27D666CD88E42B4  
This service often fall down and I don't understand why.  
Is anyone can help me.  
I'm on a Debian GNU/Linux 8.5 (jessie)
