When I want to run my migration to create a database I get this error:
2024-01-12 16:28:38 Cannot load library libgssapi_krb5.so.2
2024-01-12 16:28:38 Error: libgssapi_krb5.so.2: cannot open shared object file: No such file or directory
Error happened on context.Database.Migrate():
using (var serviceScope = app.ApplicationServices.CreateScope())
{
var context = serviceScope.ServiceProvider.GetRequiredService<T>();
context.Database.Migrate();
}

This problem only happens on ASP.NET Core 8, it's working properly for .NET 6.
I think I have to install libgssapi_krb5.so.2 on the docker image that I created, but I could not find how to do it.
If you have any experiences in this case, please share it.
as I understand, this error caused my program to crash, but I could not get any exception error in the catch part.

what did I do? I changed my base image from aspnet:8.0 to aspnet:8.0-jammy-amd64, After this change, I could get an error message in the catch part.
That error was about my connection string, I had to add this option "Trusted_Connection = false" to fix this issue.
