Aspose.PDF 26.3 aborts on Ubuntu 24.04 with ICU 74 and OpenSSL 3

[scelarek]

Environment

• Package: aspose-pdf==26.3.0
• Python: 3.12.8
• Platform: Heroku-24, based on Ubuntu 24.04, x86_64
• System libraries: ICU 74 and OpenSSL 3 (the versions supplied by Ubuntu 24.04)

Minimal reproduction

python -c "import aspose.pdf as pdf; pdf.Document()"

Actual behavior

The process terminates through .NET fail-fast instead of raising a Python exception:

Process terminated. Couldn't find a valid ICU package installed on the system.
Aborted (core dumped)

The process exits with code 134 even though Ubuntu's libicuuc.so.74 is installed.

Setting invariant globalization gets past the ICU check:

DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1 \
  python -c "import aspose.pdf as pdf; pdf.Document()"

but exposes a second native dependency failure:

No usable version of libssl was found
Aborted (core dumped)

Ubuntu 24.04 provides OpenSSL 3 / libssl3; it does not provide the EOL OpenSSL 1.1 package in its normal repositories.

Because both paths abort the process, application-level try/except cannot handle the failure. In a worker process this kills the entire job.

Expected behavior

Aspose.PDF for Python via .NET should:

1. initialize on a current Ubuntu release using its system ICU 74 and OpenSSL 3 libraries, or document a supported modern-Linux configuration that does not require EOL libraries; and
2. return a catchable Python exception when native prerequisites are unavailable rather than terminating the hosting process.
