Installtion fails caused by non existend files

[crackscout123]

Platform: Ubuntu 18 LTS
Server type: Apache2
PHP version: 8.2

The installer is looking for two files which dont exsist called "INSTALLING" and "INSTALLERLOCK".
I tried to work around it by creating a empty file called "INSTALLERLOCK" this works in the first place, I can go to the next step BUT now its looking for the "INSTALLING" file. I tried the same method with the empty file (and added permission so it can be accessed) but it does not work.

Here the Exception:

Your file permissions aren't set correctly.
Make sure all files are owned by the Apache group and user. In Ubuntu in most cases this is the www-data group and user.

sudo chown -R www-data:www-data /path/to/littlelink-custom

Next enabled all members of the www-data group to read and write files

sudo chmod -R g+rw /path/to/littlelink-custom
