Self hosted, tried to update to the latest version, and all fell apart.

Common recent report - you just upgraded to node 18, right? If so, check this thread: > [@Upgrade ghost 5.71.0 with node 18, encountered error](https://forum.ghost.org/t/upgrade-ghost-5-71-0-with-node-18-encountered-error/42246/3): > > Yes, I have the same issue. Still can’t fix it. Mysql is running, nodejs is already the newest version (18.18.2-1nodesource1). Tried ghost setup, still no success If that’s not it, I’d start by investigating whether mysql is running. But start with the link above. I’m betting that’s it, because I see Ghost trying to connect to the ipv6 address… which is a change from Node 16. ---

Hi, No luck with 127.0.0.1. Trying to run mysql but error occurs: ERROR 1045 (28000): Access denied for user ‘root’@‘localhost’ (using password: NO). I also think that mysql is not running. ---

Looks like a root+mysql password error? You can run `sudo mysql -p` to get it to ask for the root password. You can also look in the `config.production.json` for the user/password your blog is using to login to MySQL - and `mysql -u [ghost-user] -p` and enter the config password to confirm Ghost can connect to the db. To see the status of MySQL `sudo systemctl status mysql` and check that it is Active. To see if MySQL is actually running, `sudo netstat -leapn | less` shows all listening services on your host - if you see `127.0.0.1:3306` then MySQL is up and running. ---

I have the acces and I tried with the pass, but still no: **-bash: syntax error near unexpected token `)’** **sudo systemctl status mysql** ● mysql.service - MySQL Community Server Loaded: loaded (/lib/systemd/system/mysql.service; enabled; vendor preset: enabled) Active: active (running) since Sun 2023-11-05 20:24:29 UTC; 1 day 6h ago Process: 720 ExecStartPre=/usr/share/mysql/mysql-systemd-start pre (code=exited, status=0/SUCCESS) Main PID: 816 (mysqld) Status: “Server is operational” Tasks: 38 (limit: 2309) Memory: 435.4M CPU: 13min 38.881s CGroup: /system.slice/mysql.service └─816 /usr/sbin/mysqld Nov 05 20:24:21 Bilbord systemd[1]: Starting MySQL Community Server… Nov 05 20:24:29 Bilbord systemd[1]: Started MySQL Community Server. ---

Did you see @Cathy_Sarisky post - that is most likely the issue. I think they are saying to change “localhost” to “127.0.0.1” in the database section of your `config.production.json` ---
