Discover tray icon shows 'Up-To-Date' when updates are available

[accounts0]

The tray icon says green checkmark & when I click it it says there's 1 update available. But when I click the 'Update' button & Discover launches it shows there being more than 1. Same in Synaptic.

Does this happen frequently or only today?

Does this happen frequently or only today?

Happened when I was using KDE Neon User Edition, but never on this box until just recently.

Since it's not always on to run unattended-upgrades properly I have a cron job that runs 'aptitude update' every 30 minutes, & I used to occasionally see the icon turn red all of a sudden then I'd take care of it right then. But today this isn't happening. What I saw after expecting a red icon there is how I found out its not right anymore.

There may have been issues today. I too didn't see updates available. But after checking in konsole, there they were:

Shouldn't be necessary. Ubuntu is well aware that most computers aren't on 24*7 (and most that are, are wasting energy), so the unattended upgrades don't run at a fixed time of day using cron. Instead, they run at a random number of minutes after boot.

I don't know if it applies here, but have you read about phased updates (https://wiki.ubuntu.com/PhasedUpdates)?

designed to be run from cron (e.g. via /etc/cron.daily/apt (file:///etc/cron.daily/apt))

I'm actually not sure I got it configured properly, since I didn't understand how to do this part- my crontab & sudo crontab didn't include anything like this by default that I could uncomment, & I think I read somewhere that the cron based scheduler was obsoleted by a systemd timer of some sort that I had no desire to get sucked into trying to figure out -likely over the course of days, lol! I just put it off & make clunky workaround scripts.


but have you read about phased updates?
No, but that looks interesting. I wonder how they handle pushing urgent updates like for heartbleed, etc. Hopefully there's no delay there. I see it only applies to the "Update Manager" update manager, & not the "Discover" update manager that's standard in Kubuntu. I installed it to have a look & it's not immediately clear how I'd swap out Discover for Update Manager. There's no section to choose from in "'System Settings' > 'Applications' > 'Default Applications'", where I'd expect to see an entry in the left column to select which system tray package updater to use/launch by default. I'll just stick with Discover since it's integrated & at least the tray icon works, which seems difficult for more apps than I'd expect. eg. I have to pin an old Thunderbird Mail to run an old system tray extension that hasn't been updated in years. :-(
