I upgraded this machine to 19.04 sometime just before the official release. I want now to track down the start of an issue I'm having and need to know when I did that.



The top line of /var/log/apt/history.log seems likely but I don't see anything really convincing.



What would I look for?

You can get the date by looking in /var/log/dist-upgrade/history.log. But a more "behind-the-scenes" and informative file is /var/log/dist-upgrade/main.log.
