Install issue Aspose PDf .net on Ubuntu 20.04

Aspose.PDF Product Family
1

Installed dotnet core sdk and nuget.

nuget gives me this.
Attempting to resolve dependency ‘System.Security.Permissions (≥ 4.5.0)’.
The ‘System.Security.Permissions 4.5.0’ package requires NuGet client version ‘2.12’ or above, but the current NuGet version is ‘2.8.7.0’.

Tried upgrading nuget, get this:
Could not load file or assembly ‘System.Net.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’ or one of its dependencies.

Was successful a few months ago. Not sure what changed.

It looks like the issue is specifically related to the NuGet Version in Ubuntu 20.04. You may please try to update the extension by going into the extension manager in VS. Also, you can check in the project directory and find for nuget.exe file. Then manually download the latest version of nuget.exe and replace it in that folder.

The newest Ubuntu version throws the http transport errors
