Hello list, I have installed and re-installed MariaDB trying to get prelude to work and I'm at a loss. When I try to run 'sudo systemctl start mariadb.service' I get these errors: Job for mariadb.service failed because the control process exited with error code. See "systemctl status mariadb.service" and "journalctl -xeu mariadb.service" for details. so I read the KB and found I'm supposed to use 'sudo systemctl status mariadb.socket' which gives this: ● mariadb.socket - MariaDB 10.6.11 database server (socket activation) Loaded: loaded (/lib/systemd/system/mariadb.socket; static) Active: active (listening) since Thu 2022-12-29 18:39:25 CST; 26s ago Until: Thu 2022-12-29 18:39:25 CST; 26s ago Triggers: ● mariadb.service Docs: man:mariadbd(8) https://mariadb.com/kb/en/library/systemd/ Listen: @mariadb (Stream) /run/mysqld/mysqld.sock (Stream) [::]:3306 (Stream) Tasks: 0 (limit: 8190) Memory: 4.0K CPU: 2ms CGroup: /system.slice/mariadb.socket and then if I try to run 'sudo mysqlcheck -A' I'll get this error: mysqlcheck: Got error: 2013: Lost connection to server at 'handshake: reading initial communication packet', system error: 104 when trying to connect I then check the status of the socket and get this output: sudo systemctl status mariadb.socket × mariadb.socket - MariaDB 10.6.11 database server (socket activation) Loaded: loaded (/lib/systemd/system/mariadb.socket; static) Active: failed (Result: service-start-limit-hit) since Thu 2022-12-29 18:4> Duration: 1min 11.173s Triggers: ● mariadb.service Docs: man:mariadbd(8) https://mariadb.com/kb/en/library/systemd/ Listen: @mariadb (Stream) /run/mysqld/mysqld.sock (Stream) [::]:3306 (Stream) CPU: 2ms I then ran 'sudo journalctl -n 20 -u mariadb.service' (as per the kb) and get: Dec 29 19:12:45 DebianTim mariadbd[3660996]: 2022-12-29 19:12:45 0 [Note] /usr/sbin/mariadbd (server 10.6.11-MariaDB-1) starting as process 3660996 ...

I even tried the apparmor suggestion from the KB and it didn't work, I even tried stopping apparmor service completely and still couldn't get it to work. I'm using Debian testing (Bookworm) with Kernel version 6.0.0-6-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.0.12-1 (2022-12-09) x86_64 GNU/Linux and MariaDB 10.6.11 from the Debian repository. Thanks in advance for any help. -- Tim McConnell <tmcconnell168@gmail.com>
