Omnisharp C# Not Working on Ubuntu 22.04 with Unity-CodePudding

Due to Windows giving me new problems day by day, I permanently moved to Linux (Kubuntu 22.04 LTS). But while working with Unity Editor, VS Code doesn't provide me with Intellisense.

In My System: mono-complete dotnet-sdk-6.0 && aspnetcore-runtime-6.0 packages are Installed

In VS Code: "C# Extension" is Installed

Case I:-

omnisharp.useModernNet: false

Output:

Any Fix? Thank you

Ok I have solved the problem.

what I did was to remove the Microsoft Package of dotnet (sdk & runtime) and installed the snap version.

And I also completely removed mono-complete and installed it again and Voila! It works now Thanks
