I have a freshly upgraded server where I can not boot neither mysql nor mariadb. It's a virtual server that runs on Linux 2.6.32 kernel even though I've already installed the latest kernels during upgrades.
The service provider indicates that the kernel upgrade is only possible with the kernel upgrade of the host system, which is not expected in the near future.
So now I have an update of Debian 9 with an old kernel where mysql or mariadb can not be started. I do not know if this is due to the old core or something else. How can I detect the cause of the problem? It would be nice to start one of them and make my wordpress web pages work.
