Zabbix 6.4 problem: can't connect to database MYSQL

[djé13]

I recently created a zabbix via this tuto: https://www.layerstack.com/resources...IX-on-Ubuntu22 everything works until I accidentally delete zabbix-agent from my zabbix server and I launch the updates on it (apt update /upgrade) since I have this error message.

Error Message

I also have a problem of access to the MySQL database via terminal, I think of a problem of password but it is impossible to reset it via mysqld_safe --skip-grant-tables If you have any ideas I'm interested.

error message2

error message3

Thanks in advance

Deleted whole db awell? Can you log in as root to mysql and see what DB-s are present and what users are present..?

Hello, by editing the file /etc/mysql/my.cnf and adding the following commands:
[mysqld]
skip-grant-tables
skip-networking

I could make my zabbix work but if I remove these lines nothing works anymore
