I am using Google.Cloud.SecretManager.V1 in my .NET 5 aspnet core application. I am containerizing application to run as linux container on GCP Cloud run. I get following exception while creating SecretManagerServiceClient
//call SDK
SecretManagerServiceClient client = SecretManagerServiceClient.Create();
System.DllNotFoundException: Unable to load shared library 'libdl.so' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: liblibdl.so: cannot open shared object file: No such file or directory

Same code works fine if I use aspnetcore 3.1 image. NET 5 is supposed to be upgrade of .NET core 3.1 and backward compatible. So, I am curious and what could be done to make this code work on .NET 5
I posted this answer to make a solution from the comment section more visible.
As it was suggested by @John Hanley and confirmed by @SmartCoder this issue was solved by adding to the Docker file lines below:
RUN apt-get update -y
RUN apt-get install -y libc6-dev
