Problem with a linux tentacle executing steps

I have a linux container running based on mcr.microsoft.com/dotnet/core/sdk:3.1.201-bionic. The tentacle installs and runs with no issues. DotNet CLI commands are working (new, build, etc.). However, it is failing to run tasks on the server. It’s even failing on the Acquire packages step. The step output is below. Any help is greatly appreciated.
