I have been periodically (maybe daily?) been getting this error message since I virtualized my Ubuntu 22.04 partition.

enter image description here

I don't want to re-launch the application (so I have to take special care to uncheck this every time), I don't know why it's even trying to do a full upgrade without my permission, and I would like to disable it from making this attempt! If I ignore the dialog another one pops up on top of it in another day or so, so this doesn't prevent it from running again either.

When I go to "Software and Updates" it says (under the "Updates" tab) that I am "subscribed" to "Security Updates Only" but does not provide any way to subscribe to less than that. It is already set to automatically check for updates "Never". I also changed "Notify me of a new Ubuntu version" to "Never" but a day or two later and this crash report pops up again!

Update: Here is the output of the commands requested in the comments.

$ grep "Prompt" /etc/update-manager/release-upgrades
Prompt=never
$ do-release-upgrade -c
Checking for a new Ubuntu release
In /etc/update-manager/release-upgrades Prompt 
is set to never so upgrading is not possible.
$ dpkg -s unattended-upgrades | grep "Status"
Status: install ok installed

Update: Here is some of the output of the file left in /var/crash:

  • Can you add the output of grep "Prompt" /etc/update-manager/release-upgrades, do-release-upgrade -c, and dpkg -s unattended-upgrades | grep "Status" to your question? – DynamicBits Feb 01 '23 at 02:56
  • @DynamicBits Thanks, I have added that info – Michael Feb 01 '23 at 15:27

It looks like the unattended-upgrades package is the root cause of that error message. You can disable unattended-upgrades a few different ways, while still allowing for manual updates when you are ready. Any one of the following methods should do the trick:

1. Change unattended-upgrades Configuration

sudo nano /etc/apt/apt.conf.d/20auto-upgrades

Change the 1 to 0 for each option (APT::Periodic::Update-Package-Lists and APT::Periodic::Unattended-Upgrade)

2. Stop and Disable unattended-upgrades Service

sudo systemctl stop unattended-upgrades
sudo systemctl disable unattended-upgrades

Verify the service is no longer running with:

systemctl status unattended-upgrades | grep "Active"

3. Uninstall unattended-upgrades Package

sudo apt remove unattended-upgrades

  • Thanks! I tried #1 but strangely both were already set to 0. However when I tried the second it showed that it was active and I was able to change that to say "inactive (dead)" with the systemctl commands. I will wait a day or so to verify that the error doesn't pop up again and hold the uninstall in reserve as the big hammer just in case. – Michael Feb 02 '23 at 15:33
  • By any chance are you running a different flavor than Ubuntu, like Lubuntu? – DynamicBits Feb 02 '23 at 16:18
  • I have installed some Lubuntu packages on top of Ubuntu - my understanding from previous feedback in a different question/answer was that it's still Ubuntu (Ubuntu 22.04.1 LTS as reported by lsb_release -a) – Michael Feb 02 '23 at 19:06
  • I believe all flavors of Ubuntu will show the same output. Lubuntu does have an updater of its own. What's the output of dpkg -s lubuntu-upgrader? – DynamicBits Feb 02 '23 at 21:01
  • dpkg-query: package 'lubuntu-upgrader' is not installed and no information is available – Michael Feb 02 '23 at 23:07

    I can't think of any other obvious sources for the error message, so I'm hoping the problem is solved. If you do get another crash report, please click "Show Details" and add that info to your question. – DynamicBits Feb 02 '23 at 23:50
  • After the first 24 hours nothing but after 48 hours it popped up again. I'm going to try #3. – Michael Feb 04 '23 at 20:13
  • The dialog popped up again after uninstalling. Should I need to reboot for any of this to take effect? I'm trying that next... – Michael Feb 06 '23 at 18:21
  • oh, sorry i just now again saw you asked for "Show Details" right after I dismissed the dialog... any way to get the info from a file? – Michael Feb 06 '23 at 18:58
  • I don't think a reboot will make any difference. There must be something else trying to start an update. The crash dumps are stored in /var/crash. Just use head on the dump to share enough info for us to hopefully find what's causing this. – DynamicBits Feb 07 '23 at 01:14
  • Thanks, I have added that info... it's calling a Python script with "lubuntu" in the name, that seems a pretty big clue? – Michael Feb 07 '23 at 15:18
  • I found this: https://askubuntu.com/a/1404298/82144 – Michael Feb 07 '23 at 15:23
  • Oh, boy.. I had the wrong package name earlier. If dpkg -s lubuntu-update-notifier shows that it is installed, sudo apt remove lubuntu-update-notifier should do the trick. – DynamicBits Feb 08 '23 at 02:35
  • hmm, welll... sudo apt remove lubuntu-update-notifier also says it is going to remove lubuntu-desktop which seems like might be bad since i'm running lxqt? – Michael Feb 08 '23 at 17:50
  • hmm, maybe not... https://packages.ubuntu.com/jammy/amd64/lubuntu-desktop/filelist. Only two text files? What's the purpose of this package anyway... – Michael Feb 08 '23 at 17:52
  • It is a metapackage. apt-cache show lubuntu-desktop will show you the depends. The end of that will say It is also used to help ensure proper upgrades, but it can be safely removed if you want to remove some applications installed by default. Since you installed Lubuntu packages on top of Ubuntu, it's not very clear to me exactly what you have installed. You may have other issues when you update to a new release. But you should be able to fix the notifier issue today and worry about that when it comes time to upgrade. – DynamicBits Feb 08 '23 at 21:27
  • Thanks, I have removed that package and hopefully will not see any more popups in the next day or two! – Michael Feb 08 '23 at 22:23
  • It seems to be fixed, thanks! – Michael Feb 11 '23 at 00:06
