I see the argument for getting security updates out there ASAP, but this case proves my point that it is a bad idea to do it automatically [unless perhaps there is a serious remotely vulnerable actively exploited issue] on any sort of production environment. Deploy to test environments and verify (at very least smoke test) first then apply elsewhere. If you don't have test environments, at least do the deploy to prod/other at your control when someone is available to quickly take action regarding any unexpected issues.
So the initial problem may be with Ubuntu, or upstream systemd, but MS policies magnified it significantly.
It seems like something at this company is not functioning well, it seems to be operated like it's no big deal, no QA, no quality and performance culture, it's a giant mess
It has infected Github too, impressive..
Google Cloud / Microsoft Azure, they have a looooooong way to go before being able to properly compete with AWS
There being a bug in the package may be an Ubuntu thing, me losing time to diagnosing problems caused by the update getting applied without my knowledge is very much an MS/Azure problem.
At least this incident gives me fuel for strongly suggesting that we turn unattended-updates off and darn well keep it off (obviously we need to keep alerts on, but we should install updates in an orderly manner, when we can monitor the results and smoke-test, preferably applying to test resources before uat/prod/other).
