1. Install NSS Library: On most Linux distributions, you can install the required NSS library through the package manager. Depending on your distribution, use one of the following commands. For other systems, please refer to the operating system's dependency installation documentation:

   • Ubuntu/Debian:

     sudo apt-get update
     sudo apt-get install libnss3

   • CentOS/RHEL:

     sudo yum install nss

   • Fedora:

     sudo dnf install nss

2. Check Library Files: After installing the dependency library, check if libplc4.so is in the system's library path. You can use the find command to locate this file:

   find / -name libplc4.so

After performing the above operations, try running the PDF and PNG export operations again, and they should be successfully exported. If the problem persists, ensure compatibility between the system architecture and related software versions.
