Unable to run new Project on Ubuntu 24.04 - liblibSkia not found and glib_2.33 issue on glib_2.39 System

[MarcoGriep88]

Hi, i'm having some issues on running my newly generated Project in AvaloniaUI on .net 8.0 and Ubuntu 24.04.

I already installed nuget package: SkiaSharp.NativeAssets.Linux and also tried "NoDependencies". I'm not sure if the issue is in glib_2.39, because 2.33 is referenced.

StackTrace:

/home/marcogriep/RiderProjects/AvaloniaApplication1/AvaloniaApplication1/bin/Debug/net8.0/AvaloniaApplication1

I hoped that glib 2.39 would be downwards compatible ^

You are using .NET SDK or IDE from Snap. This is not supported and will not be supported.

Install the SDK using .deb packages, preferably from the microsoft repository and not the botched ones from ubuntu repositories.

Ah okey, thanks :) I will try this.

I uninstalled dotnet-sdk-8 snap package and installed debian package version. Works like a charm. Thanks alot.

Same thing worked for me, just install using sudo apt install dotnet-sdk-8.0 the Microsoft packages are no longer being pushed for 24.04 and onward, see: https://github.com/dotnet/core/blob/main/linux.md
