I am using 24.04, Noble whatever…
My Lubuntu update program has 75 “security related” updates waiting in the que but my install updates button is inactive. Being fairly new to Lubuntu I have to ask if this is a common occurance or is there something wrong with my system?
Welcome to Ubuntu Discourse 
Open a terminal and post the output from these 2 commands one after the other:
sudo apt update
sudo apt full-upgrade
If there are errors, we should see them.
When you copy and paste the content here please highlight and use Ctrl+E to wrap with code tags.
Thanks.
Hello and welcome to the Ubuntu Discourse Community
Have you tried restarting your system and try updating the system again? sometimes a simple restart will do wonders
I shut my system down every time I log off so restarts haven’t solved the problem. I did do the manual process from rubi1200 and it worked. However I haven’t had any new updates since then so I don’t know if the new ones will get stuck. We shall see.
The manual process produced 9 pages of text in Libre Office so I won’t post the whole thing here. A week or so ago I installed Bleachbit on my system and used it once. It was not a clean install but it ran ok afterward so I did not give it any thought.
The manual upgrade made me stop and do a fix on Bleachbit as shown below:
The following packages have unmet dependencies:
bleachbit : Depends: python3-psutil but it is not installed
Recommends: python3-notify but it is not installable
Recommends: python3-scandir but it is not installable
Recommends: gir1.2-ayatanaappindicator3-0.1 but it is not installed
After the Bleachbit fix everything upgraded smoothly. Could this be the reason for the hangups?
I’m glad you were able to get it sorted out hopefully it will continue to run smoothly.
You could run the commands I gave you again and see if there are any errors.
No need to post all the output, only the last few lines where errors are usually reported.
If no errors, you should be fine.
Yes, that suggests something very wrong.
Security Updates should generally not be “queued” at all.
On a properly-working Ubuntu system (including Lubuntu), your system should check for and install security updates several times daily and entirely automatically. You shouldn’t even notice it happening.
Unless, of course, you disabled that feature.
Ubuntu help venues have a long history of folks complaining about damage caused by Bleachbit. Learn how to use it wisely so you aren’t one of them.
Ubuntu is not like Windows. Windows habits (like the profligate use of Bleachbit) may lead you to trouble.
Ubuntu (including Lubuntu) is designed to be a safe-by-default and secure-by-default OS. You generally don’t need tweaks or add-ons to “harden” or “secure” it further. Open Source developers care deeply about user safety, security, and privacy, and they take great pride in their work.
FYI. I was able to perform another update using the updater and it worked fine. Case closed and thank you for your help.
Please mark the relevant post as the solution.
It helps the community finding solutions when facing the same or similar issues.
