[SOLVED] Error with MariaDB after update to Debian 10

[lilp]

Hi,
I just upgrade CT to Debian 10, and now I can't start mariadb.
I have this issue :
mariadb.service - MariaDB 10.3.23 database server
Loaded: loaded (/lib/systemd/system/mariadb.service; enabled; vendor preset: enabled)
Active: failed (Result: exit-code) since Sun 2020-09-06 13:33:20 UTC; 1 day 1h ago

How can I solve this issue?

Thanks.

Please post your CT config and your pveversion -v:

> pct config CTID

> pveversion -v

I enable nesting in LXC .conf and it's works.
