Ubuntu 16 to 22.04 turn down ispconfig even update is not working either

I have upgraded to ubuntu 22.04 from 16 but I didn't know ISPConfig 3.1 will turn down. I downloaded 3.2.9. I am getting error on upgrade as well as not able to reinstall keep showing error. I am worried about data which is present throuhg it. Here are the below issues when i tried update.php

>> Update

Operating System: Ubuntu 22.04.1 LTS (Jammy Jellyfish)

PHP Fatal error: Uncaught Error: Call to undefined function get_magic_quotes_runtime() in /usr/local/ispconfig/server/lib/config.inc.php:48
Stack trace:
#0 /tmp/ispconfig3_install/install/update.php(112): include_once()
#1 {main}
thrown in /usr/local/ispconfig/server/lib/config.inc.php on line 48


Need urgent solution on this.

 

I tired to update but same error I had been getting but now I am trying to remove / uninstall but I am not able to do that too.
What's the best possibility? I am am trying to up sites manally thorugh apache as I can't find proper way to fix it on u22.04

 

location of config.inc.php ?

 

I have just commit the below line:
#if(get_magic_quotes_runtime()) set_magic_quotes_runtime(false);

What to do next?

 

I have just tried to update through update command and it's asking me stable version so, I select that and now it's saying ubuntu 22.04 unknown and php version 8 is not supported

 

I selected now with git-stable and its backing up files and lets see afterwards.

 

I just did this and now it's stop by saying this:

Checking ISPConfig database .. WARNING: Forcing protocol to TCP due to option specification. Please explicitly state intended protocol.
mysqlcheck: Got error: 1698: Access denied for user 'root'@'localhost' when trying to connect
OK
WARNING: Forcing protocol to TCP due to option specification. Please explicitly state intended protocol.
ERROR 1698 (28000): Access denied for user 'root'@'localhost'
Unable to call mysql command line with credentials from mysql_clientdb.conf

What could be the reason here?

 

Given details are right but when I tried to check db with the name of dbispconfig. there is no table in their. What does it mean?
Do I need to create new database and old data is deleted from database ?

 

That's fine. I will add credentials myself again. All I will have to add sites and ftps thats it because rest I had been managing externally.

 

How should I create new database? Do I just have to delete that file and update process accordingly?

 

I can only see these three things in backup folder
ispconfig_db_backup.sql and it's contains:

dump date is today's one.

I am tired now with this.
I am trying to install new totally by removing database and its config files. After starting its updating almost everything and checking everything and keep giving errors on different points like on antivirus clamav it got stuck so, I disable that and than keep on other things. Need urgent solution on this.
