To answer: > How are you running Python 3.9 in Focal?
We installed Python 3.9 from Focal's upstream. No third party. > Are you using the cloud-init package provided by Apt? Yes, because we started to see the issue after the OS update. We switch AMIs, thinking that the OS update was problematic (which is was, but not the way we thought) > Your error shows a crash due to the jinja2 library not existing, but jinja2 is a dependency of cloud-init. The python3-jinja2 package should have been installed when you installed cloud-init. Up until now, cloud- init could still run without this dependency installed, but that doesn't change that it has been a dependency, so I don't see evidence of a problem here. We wouldn't know that python3-jinja2 is required, as we don't usually manage cloud-init - we generally left it alone - at least until the issue began. We can test to see if installing python3-jinja2 moved us forward.
