[debian-mysql] Bug#839130: mariadb-server-10.0: mariadb-server stops after each apt install related command

[fguerin]

Package: mariadb-server-10.0
Version: 10.0.27-0+deb8u1
Severity: serious
Justification: unkwown

Dear Maintainer,

I'm using mariadb-server 10.0 on a production server, taken from the debian standart repository. 
I've instelled unattended-updgrades on the server, updates / upgrades are performed automatically every days.

For a while, the server stops, due to an attempt to upgrade, with a dpkg --configure error: 

$ sudo apt install
...
dpkg: erreur de traitement du paquet mariadb-server-10.0 (--configure) :
 le sous-processus script post-installation installé a retourné une erreur de sortie d'état 1
dpkg: des problèmes de dépendances empêchent la configuration de mariadb-server :
 mariadb-server dépend de mariadb-server-10.0 (>= 10.0.27-0+deb8u1) ; cependant :
 Le paquet mariadb-server-10.0 n'est pas encore configuré.

dpkg: erreur de traitement du paquet mariadb-server (--configure) :
 problèmes de dépendances - laissé non configuré
Des erreurs ont été rencontrées pendant l'exécution :
 mariadb-server-10.0
 mariadb-server
E: Sub-process /usr/bin/dpkg returned an error code (1)

I've to manually restart the server:

$ sudo systemctl restart mysql

I've tryed to mark "hold" the package, but the issue still appens.

Thanks for your help !
