Installation troubles on Ubuntu 16.04-18.x with xampp

/files/config/parametersLocation.php contains:
$parametersLocation = '../files/config/parameters.php';
File: /files/config/parameters.php contains:
$logFile = '../files/logs/projeqtor_${date}.log';
$logLevel = '2';
But I see the file contains the same data twice including: TEST<?php
So, maybe this file was broken?

So, now I can proceed to the login page.
But the message is shown before authorization: Upgrade in progress. Only admin user can connect.
After trying to login I get two more errors:
1) an error: An error occurred on 2020-01-20 at 11.22.43
2) "max_input_vars=1000 is too small - value should be at least 2000, 4000 recommended - check your php configuration (php.ini)"
Although the /opt/lampp/etc/php/ini has parameter: max_input_vars=4000

Appeared the log file. New error time: 2020-01-20 13:23:40
