Start with the linked GitHub Actions job and the failing org.janusgraph.pkgtest.InMemoryAssemblyIT.testJanusGraphServerGremlin test. Read AbstractJanusGraphAssemblyIT.testServerUsingTraversalSource, runTraversalAgainstServer, and testJanusGraphServer to trace the missing [g] traversal source; done means the distribution tests pass on Ubuntu 20 without this error.
