Hi,

I have a cluster with 3 nodes running fine, behind a HAProxy. All on Ubuntu 16.04.  
Tody I tried to upgrade one backup node with apt-get and i got the folowing error :

I tried to another node, same result…

Thing really strange, after reboot, look like the cluster is upgraded but my apt still report an error.

Could you help me to fix ?

Best regard

Hi,

Can you please show the list of installed packages:

```auto
dpkg -l | grep percona

```

Mysql error log would also be helpful.

Hi

There is a trouble with /etc/init.d/mysql script.

I had to comment the mysqlping.

The command return “false” then for the script service is not started so update is not finished…

I don’t know why ☹
