Question In which cases is the "Package Update Manager notification" sent (what's the logic behind it)?

[King555]

I have to admit that this question is not vital, but I'm curious. And also I think that I get too many notifications, which is more annoying than useful.

When new updates for my system are available, Plesk or the "PUM" sends a "Package Update Manager notification" via mail.

I did not install updates for 1.5 weeks ( I will do it now) and while viewing the list of mails today, I wondered why I get mails sometimes daily, then only every second day. And sometimes there are no new updates compared to the previous mail, sometimes there are.

Is there a logic behind this behaviour? In my opinion, there should only be a new notification when additional updates are available. Or, to remind of updates, every X days. Currently it does not make sense to me.

And there is an additional thing to mention (but I have to check it again today/tomorow to be sure): When I install all the updates, I still get the notification on the next morning. It looks like the mail is sent before checking for updates. But as I said, I have to verify this behaviour. I think I will open a bug report if this is happening again. The main question of the thread is only a question and I don't think I have to post a report.

Concerning the possible bug I created a report today: "Package Update Manager notification" is sent before checking for (new) updates

It turned out that indeed the notification mail is sent even when no more updates are available at that time.

So there's only my question left, when (in which cases) exactly the notifications are sent.
