Hi, im getting this error when trying to run my umbraco on ubuntu: Unhandled exception. System.TypeLoadException: Could not load type 'Microsoft.AspNetCore.Builder.IISServerOptions' from assembly 'Microsoft.AspNetCore.Server.IIS, Version=9.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. I installed umbraco 15 and dotnet 9 does anyone know what can be the problem?

IIRC, a manual net9 SDK install is needed on all unixes... https://our.umbraco.com/forum/using-umbraco-and-getting-started/115012-cut-by-the-bleeding-edge-has-anyone-managed-to-get-u15-stood-up-on-linux

thanks. its working

Yep, some others have been having the same issue: https://discord.com/channels/869656431308189746/1308102704861675631/1308102704861675631 Seems there is maybe something up with the .NET 9 APT package specifically.
