Hi Yall, I have just upgrade my qatrack to branch 3.1.1.4 in a new VM.

I have installed Ubuntu 24.04.2 LTS, with python 3.9.22 and pylinac 3.33.0.

I am trying to gets some pdf reports in PDF mode thruoth the review area for a specifit test list, but it´s not working Error 500 : Server Error

I went to the folder \\192.168.10.11\qatrack\web\qatrackplus\qatrack\media\reports did not find the pdf and the logs \\192.168.10.11\qatrack\web\qatrackplus\logs show no error.

In the folder reports i saw some hmtl that looks like is the file to convert into pdf, but is all strange without any format.

Just to register my pip list in VENV

Reading other question I did some test without any success.

Tested if Chrome is installed.
qatrack@qatrack-server:/var/log/apache2$ which google-chrome
/usr/bin/google-chrome
qatrack@qatrack-server:/var/log/apache2$ which chromium-browser
qatrack@qatrack-server:/var/log/apache2$ google-chrome --version
Google Chrome 135.0.7049.114
qatrack@qatrack-server:/var/log/apache2$

I did the permission

sudo chown -R www-data:www-data /home/qatrack/web/qatrackplus/qatrack/{media,static,cache}
sudo chmod -R ug+rwxs /home/qatrack/web/qatrackplus/qatrack/{media,static,cache}

looked /var/log/apache2/error.log

I solve the error 500 in my VM to save pdf file. The problem was the Chromium instalation.

1-uninstall chromium

sudo snap remove chromium

2- install
sudo add-apt-repository ppa:saiarcot895/chromium-dev
sudo apt update
sudo apt install chromium-browser

also can check the version installed
which google-chrome, for linux should be /usr/bin/google-chrome

I set in local_settings.py a new variable in the end of the file
CHROME_PATH = "/usr/bin/google-chrome"

3-restart apache2

sudo systemctl restart apache2

Happpy QA to yall!!!
