updates should be listed immediately after checking

[Nick]

Ubuntu 18.04.2 LTS is on my spare laptop, so I hadn't used the OS in about two weeks, which is when I had last updated it. I do not use the update feature that requires logging in when I'm in an insecure environment for password use. I was about to use the laptop again, so I checked for updates and Ubuntu said there was nothing new. I put it to sleep and woke it about 30-60 minutes later, somewhere else, where my session time could be short. When I logged into a WiFi network, a dialog said there are updates and asked if I want them now.

What I expect: If there is an update at a Ubuntu server or mirror, Ubuntu will say so when asked, not only half an hour later.

Of course, it's possible that when I check there is no update but if I check half an hour later there will be an update. That's a different situation and completely acceptable. But if telling me that there's an update will take half an hour, tell me that it'll take a while, but don't tell me right away that there's nothing.

This event happened in late May. I saw the list of packages but don't know which one applies. No crash occurred on my platform. The dialog from ubuntu-bug had nothing relevant to an update (I understand upgrade is different), so I selected Other, resulting in nothing informative. ubuntu-bug --help didn't lead to an answer, either.
