we have the same problem here. After replacing the file, it now throws the following errors: 20.01.2023-10:06 - WARNING - There is already a lockfile set, but no process running with this pid (6349).

In our case it is an existing system with Debian 10 and ISPConfig 3.2.9. The error occurred when creating a shell user.
After replacing the file it now throws the following error: 20.01.2023-10:18 - WARNING - There is already a lockfile set, but no process running with this pid (25597). Continuing. PHP Fatal error: Cannot declare class shelluser_base_plugin, because the name is already in use in /usr/local/ispconfig/server/plugins-available/shelluser_jailkit_plugin.inc.php on line 31
I moved your posts to a new thread, as the other thread is about the Migration Tool only and also about a different file. Please post the output of the command: php --version To me, it looks like you changed the default PHP version, which is PHP 7.3 on Debian 10, to a different version like PHP 8.1. This is not supported by ISPConfig as mentioned hundreds of times in the forum already. Never change the default PHP version of the OS, as it breaks ISPConfig and also other packages of your system that use PHP. You can use newer and older PHP versions as additional PHP versions in ISPConfig, the default version only changes when you upgrade the OS.
Just as info. I added a few more changes to avoid the above error on Ubuntu 22.04 systems, which is currently the only OS that uses PHP 8.1 as the default PHP version: https://git.ispconfig.org/ispconfig/ispconfig3/-/merge_requests/1689/diffs
