Description

I am currently testing a Tiki 24 trunk as a local office software on my work laptop.
The Tiki is still in the process of configuration, setup and testing.

I use a Mint/Ubuntu 18 Linux. I use a standart Apache2 / Mysql/PHP (7.4/8.0) installation, each part installed with the command line (not a prepacked Xampp/Lampp).
Side note to PHP version:
I could not install Tiki with PHP 8.0 (WSOD issue) and did install it then with PHP 7.4 running
Later when I installed a number of Packages, Tiki requested PHP 8.0 and it stopped working with PHP 7.4 (WSOD). Thus this Tiki 24-trunk is currently running on PHP 8.0

I have also a number of file permission errors and some issue with a search index error message, which I will report later on in the forums or with another bug report.

Tiki is installed via SVN and runs in /var/www/html/tiki .

One of several issues with my Tiki trunk installation is, that instantly after installing Tesseract OCR in Tiki via Packages, I get the following type of error messages:

I have definitely Tesseract installed on my laptop, but I do not (yet) know the installation path:
