Try opening a terminal and type in these two commands.
Code:
sudo apt-get update
sudo apt-get upgrade
That should tell you what your problem is. If there is no problem it will update your system.

Hi jdk,
I ran both commands. They completed with no errors but the problem persists.
The changes to Update Manager preferences I referred to in my earlier post go back to when I first installed Linux. I followed this advice which I found on a tips and tweaks website:
Improve Update Manager
1.2. The settings of Update Manager need to be improved. You can do that as follows:
Enable security updates for level 4 and 5
1.2.1. Security updates of level 4 and 5, are being shown by default. But they're not enabled by default. It's best to change that like this:
Menu button - Administration - Update Manager
Panel Update Manager: Edit - Preferences
Tab Levels (first tab): tick:
Always select and trust security updates
See the attached screenshot.
I was able to make this change with no trouble. I did not alter the preferences on update manager again until I noticed the shield icon had disappeared.
I couldn't see where Update Manager got its original icons from so I downloaded some from the web and saved them to my documents folder.
I went to Edit Preferences in Update Manager and, from the icons tab, navigated to the icons I had downloaded. Update Manager uses 6 icons to indicate its different states. I selected all 6 icons in tun, clicked on Apply then closed the preferences box and Update Manager.
When I re-opened Update Manager and went back to preferences, the shield icons had disappeared, it was as if I had never made the change.
To see whether this was just a problem with shields and icons, I went back to the Levels tab and unchecked "Always select and trust security updates". I clicked on apply and closed the preferences box then closed update manager. When I re-opened update manager and went back to the preferences, the check against "Always select and trust security updates" had re-appeared, again the change I had made had not been applied.
This appears to be a problem only with applying changes to preferences in update manager. If I go into Update Manager from the menu it is working properly. There is a gap on my system tray where the update manager icon used to be, if I click in that gap, Update Manager opens.
There is another suggestion on this thread that something in my home folder may have been corrupted. That seems a reasonable suggestion so I will take the advice and create a new user to see if that fixes the issue. I will reply when I have done so.
