Hi everyone,
I’m attempting to install aspose.Slides on Linux via Docker and am using a setup similar to the one posted here:
Aspose.Slides for .NET - No Usable Version of Libssl Found with Linux Server.
However, I run into the error:
No Usable Version of Libssl Found with Linux Server
The issue is I cannot downgrade my openssl version to 1.x.x as it is not part of my company’s repos and it is against company policy to simply “wget” a package and build from source.
How can I resolve this? What are my other options?
@nikhil.x7
Could you please provide more details about your current environment, such as the version of .NET you are using and the specific Linux distribution in your Docker container?
I am using the .NET bundled by the python package procured from pypi: aspose.Slides (version 24.10.0)
I am using a RHEL 9 image.
@nikhil.x7,
Thank you for contacting free support. I need some time to check the problem. I will get back to you soon.
We are using RHEL 9.4
We are trying to get around this issue by installing dotnet sdk 8.0 as well. How can we point aspose.Slides to use the pre-installed dotnet sdk (8.0) ?
@nikhil.x7,
Thank you for the additional information. I will contact you a little later.
@nikhil.x7,
We have opened the following new ticket(s) in our internal issue tracking system and will deliver their fixes according to the terms mentioned in Free Support Policies.
Issue ID(s): SLIDESPYNET-238
You can obtain Paid Support Services if you need support on a priority basis, along with the direct access to our Paid Support management team.
So looks like aspose.Slides via .NET framework forces us to use a lower version of OpenSSL and therefore will not be an appropriate long term solution.
I can try with aspose.Slides via Java as well.
Is the API of this package 1-1 with the aspose.slides Python via .NET?
Are there any missing features/limitations with using this?
My worry is that Powerpoint is a Microsoft product and therefore likely works better with .NET.
Please let me know the differences between the 2 packages in terms of the features, the performance, and the stability.

Thanks
@nikhil.x7,
I am working on your questions and will get back to you soon.
@nikhil.x7,
Aspose.Slides for .NET is an original library in Aspose.Slides product family. All other libraries and packages are usually ported from it. The functionality of Aspose.Slides is the same for Java, C++, Python, etc. Unfortunately, I have no information about the performance and stability comparison of these libraries.
Are you saying Aspose.Slides is originally done in .NET
and all the other packages are ported from this?
so even aspose.Slides for Java is a port of the .NET package?
@nikhil.x7,
Yes, Aspose.Slides for Java is also ported from Aspose.Slides for .NET.
@nikhil.x7,
Our developers have investigated the case logged in the ticket SLIDESPYNET-238. At the moment, Aspose.Slides for Python via .NET works in the following way: the bundled .NET runtime is called from Python code via the C++ layer. Work with any other .NET runtime is not designed. At this moment, the .NET Core 3.1 runtime is used for Windows, Linux, and MacOS x64 platforms. Switching to the .NET 6 runtime is planned and will be implemented later. The .NET 6 runtime will allow you to use OpenSSL 3. Installation for any .NET SDK or runtime will not change how Aspose.Slides for Python via .NET product works.
