Bump ubuntu package versions to fix python3.8 bug

Currently, the upstream version of python3.8 is higher than the version
used in release train. This can cause an error if python is installed before the
release train apt config is deployed but related packages,
e.g. python3.8-venv, are not due to a version mismatch.
