yarnpkg signature couldn't be verified

[nollm]

I use the dotnet-postgres template with .NET 8.0 and uncomment the lines to install additional packages via apt-get.
When I build the container I get the following error.

 => ERROR [dev_container_auto_added_stage_label 2/2] RUN apt-get update &  3.2s
