I use Ubuntu at home for my personal matters, not as a "server". I shut down my computer two or three times a day and there aren't any fixed usage times. I understand that there are automated tasks set to run at particular times of the day, week or month and that
anacron are involved. Apart from not having a regular usage schedule, I'm also blessed with an imperfect internet connection. How can I know whether the various tasks, such as maintenance or updating Ubuntu's databases, are being satisfactorily completed? I came across Which logs should I pay attention to? which referred to
/var/log/crond.log but I don't have such a log nor even a log with "anacron" in the name.
I keep up with all software updates by running
apt-get update and
apt-get upgrade more than once a day and accept all updates. I don't have any performance issues that I know of.
