I have tried to auto-update to the latest version.

I had to update php to 7.4.0, which I accomplished

php -v results in:

PHP 7.4.30 (cli) (built: Jun 27 2022 08:14:52) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
    with Zend OPcache v7.4.30, Copyright (c), by Zend Technologies

Now I am getting the "We are sorry, but a MySQL - error occurred. The administrator may find more information in the syslog" error.

Any advice is appreciated.

(e.g. where to read the syslog without web interface - maybe I can proceed from there, but if anyone has more insights, any help is welcome)

The syslog is not read via the webinterface. Check your log files in /var/log/ folder via ssh.

Also, please provide information about your OS, and from what version you are upgrading.

Thank you for your reply. I believe it was bc. the php-mysql module was missing in the new php installation. I have added it and now getting a new error (in admin_updates.php?page=overview):

Uncaught exception

0 Call to undefined function Froxlor\Config\simplexml_load_file()

then you are also missing the xml extension...maybe it would be a better idea to use the apt-package which installs all these requirements

Yes. you're right. But my dist isn't supporting php7.4x ootb. I really have to update to something past Stretch at some point. But with so many customers running live, who has the time, ey?

Anyway, I am trying to get through somehow, now with xml extension working, getting:

A database error occurred

SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes

Last time the update went so smooth. But I believe it was from version 0.10...something, now updating to 2.x.. which I think is natural to meet some challenges

It really just takes a few minues tbh,,...done that a million times. We gladly offer you to do that for you

The database error also originates from too old distro, try: 

 

Ok, thank you. Additionally I had to add

innodb_default_row_format=dynamic

to fix also the indexing size of utf8 vs. utf8mb4

 

All seems to be working now.

Cheers!
