Today I received an update notification for three updates but update manager doesn't say what updates are they.

No details of updates

Does anyone have a clue what this is about? How am I to check what is to be updated?

  • What does the terminal say? sudo apt-get upgrade

    Do we have a bug report for this? If not, someone should create one. I didn't think to capture a screen shot, but you have one here that would be good to include in a bug report.

  • Could it be that the upgrade-able packages are libraries and other "system" packages, and therefore hidden? (this could be done to confuse the user less about the updated packages, (s)he would probably only care if "Firefox" is updated?)

I was getting this problem after upgrading to 18.04. Preparatory to sudo apt-get upgrade as noted above, I did

 sudo apt autoremove

That resolved the problem for me and 'revealed' what updates were available for download. Almost half-a-gig clogging up the works.


Don’t worry! I have been through this. To clarify that I did that in terminal with

sudo apt-get upgrade

and it listed the outputs. Only 3 upgrades will be there if I remember correctly.

    Even if that solved the issue, it has to be reported as a bug. Help the whole community!

  • @Lucio , I agree with your opinion.

Check for an orphaned update-manager process that may be causing the empty Software Updater window.

pgrep -fl update-manager  

You can kill all update-manager processes with:

pkill -f update-manager  

Run apt list --upgradable in the terminal to see a list of packages that can be upgraded.
