Unable to load native library. The platform may be missing native dependencies (libjpeg62, etc). Or the current platform is not supported. in linux about wkhtmltopdf-dotnet

So you're probably missing dependencies to the native htmltopdf library on your Ubuntu 18.04 server. My guess is the libjpeg62 package, but if you install the native dpkg then it will tell you. Obviously this .NET wrapper can't install native dependencies.

Maybe it's related to #28 if you're using publish. Is the .so file in any subfolder on your Ubuntu machine?

[HakanL]

Have you made sure those dependencies are installed?

the libraries of each runtime are not exported as they should, it only works on my local machine but on an ubuntu 18.04 server it does not work

[harrinson-gutierrez]

The libjpeg62 libraries even though they are installed on the server does not work, you have to copy the native libraries in the root of the publication project, you also have to install the libssl package in case you have images in https

Those steps are definitely not correct, you don't need to download DLL and DYLIB files (Windows and Mac) to your Linux install. But that being said, you shouldn't have to download any files, we have tested this to work fine in docker, but your docker image definitely has to have libjpeg62 (and possibly other dependencies) installed. You can always try run the example docker project as-is first, which is using .NET 3.1 (2.2 as you have in your example isn't out of support by Microsoft). I'm confused if you're trying to use docker, or directly in Ubuntu, your screenshot shows a dockerfile.

I'm not using docker but evidence where I get the dependencies libwkhtmltox.dll libwkhtmltox.dydll, libwkhtmltox.so

In theory the nuget should make my life easier by placing the necessary libraries internally, but curiously these are not attached as they should, because even though I install the nuget and the native libgpg62 library and run the service in Ubuntu 18.06 it does not work. But when placing libwkhtmltox.dll libwkhtmltox.dydll
libwkhtmltox.so in the main project path, it works.
