Kubuntu 16.04 update manager not working

[peter]

Whenever I check update manager for new updates, it says my system is up to date. However, when I go to console and type apt-get update and apt-get upgrade I got tons of updates.

ubiquity is the installer. changing to plasma-discover which is what drives the updates in kubuntu

We recently uploaded a new discover to proposed. Can you test https://launchpad.net/ubuntu/+source/plasma-discover/5.5.5-0ubuntu2 to see if it fixes your issue?
Thanks

I have 16.04 with plasma-discover 5.6.2-1ubuntu1 package but I still do not get notifications.

Please see screenshot attached.

Hi guys,

I'm using Kubuntu 16.10, have Discover version 5.7.5, but my automatic update notifications are not working. I never receive updates. I have to do that through Discover by searching for updates or through console. I never get notified on updates...

Kubuntu 16.04 plasma-discover Version 5.6.2 doesn't work - program and widget still shows that Software is actual. Verified on two computers.
Running shell command "sudo apt update" makes program and widget work.
I think you know the solution, because plasma-discover on Kubuntu 17.04 works fine.

[josefko (jkotarba)]

My simple workaround which forces discover to work as expected:

sudo apt-get install cron-apt
sudo rm /etc/cron-apt/action.d/3-download
sudo ln -s /usr/sbin/cron-apt /etc/cron.daily/cron-apt

It installs cron-apt package, removes default action: download of packages for upgrade and starts "apt-get update" automaticaly daily, more or less within one hour after session start. If there is something to upgrade you can see immediately after cron-apt "apt-get update" Software updates widget in the system bar.

As of May, 1st, 2017 this bug still persists and affects the two machines in my network. If I can supply further information, please tell me which information you require. I suggest changing the status back to "incomplete".

Nevertheless, thanks for all the great work you put into (K)ubuntu!

Sometimes Update Manager doesn't talk to widget, see picture
