Recurring pyramidPrinter startup failure on Ubuntu 20 after application updates

Hi!
We are experiencing a recurring issue that is consistently reproducible in versions 2024.X and 2025.X in our environment running Ubuntu 20.

Steps to reproduce:

1. We update the application version on the environment.
2. After startup, the application fails to launch the internal pyramidPrinter process
3. The following error appears every second in the logs: "Can't create process at schedule." (full error text and screenshot are provided below).
4. As a result, the export and print functionalities become completely unavailable.

 

Temporary workaround:
To resolve this issue, we perform the following manual steps in the terminal:

1. sudo apt-get update
2. sudo apt-get install -y libpangocairo-1.0-0 libx11-xcb1 libxcomposite1 libxcursor1 libxdamage1 libxi6 libxtst6 libnss3 libcups2 libxss1 libxrandr2 libgconf-2-4 libasound2 libatk1.0-0 libgtk-3-0 libgbm1 libxshmfence-dev
3. Navigate to /opt/Pyramid/core/prt/puppet and execute: sudo chmod 777 pyramidPrinter
4. Navigate to /opt/Pyramid/core/prt/puppet/chromium and execute: sudo chmod 777 chrome
5. Return to /opt/Pyramid/core/prt/puppet/ and execute: ./pyramidPrinter --tabs=1 --port=3002
   Once the PUPPET-INITIALIZED message appears, press Ctrl-C.
6. Restart the Task Engine service either via the web interface or by command: sudo systemctl restart pyramidTE

This approach is highly inconvenient and poses a critical blocker for us: all manual changes must be reapplied after every single application update, and during these actions, the affected functionality becomes unavailable.

Are there any other ways to resolve this issue permanently?
