package manager not updating itself

Can you give the full output of:

sudo apt-get update; lsb_release -a

Thanks

Open a terminal by pressing CTRL+ALT+T enter the following command

lsb_release -a;sudo apt-get update && sudo apt-get upgrade

If you get errors post the output and we can advise further.

hi Andrew here is the output you requested.

Hi Andrew,
keyed the commands into terminal but has not had any visible effect on the package manager message.
Also rebooted to see if this changed things but no still says packages last updated 89 days ago.

https://help.ubuntu.com/community/PackageManagerTroubleshootingProcedure

Please post full Terminal output here:

https://answers.launchpad.net/ubuntu/+source/apt/+question/231222

Helo Mark,
Have just gone through the process outlined in "Package Manager Troubleshooting Proceedure" in the link you sent me.
Completed step1.step2. got to stepthree and closed all programs. I then noticed the red warning triangletelling me to manually check for updates was still showing. Thought I had better run this as well before carrying out steps 4 and 5.
As soon as I pressed the check for updates the package manager message corrected itself.
Clearly there is some conflict between the PPA's and the package manager which is causing the problem.
Do you still want me to run steps 4 and 5 and send you the output?

Yes please.

Ok Mark,
The acid test is of course what happens when I reactivate my PPA's. Will
set as solved for now and monitor the situation. If Update Manager
stalls again I will let you know. Thanks for the help.
Peter Jordan

That's the thing. If you start adding PPA's that do not support your specific release of Ubuntu, then you can expect lots of problems. Not all PPA's support ALL versions of Ubuntu. You have to be careful before adding any PPA.

If you really need to use the package in the PPA and if the PPA supports your Ubuntu release, then I suggest only keeping ONE PPA active at a time. If you activate several PPA's at the same time, you can expect even more issues down the road...

PPA's are not official Ubuntu repositories and are not officially supported....

And once the package from a specific PPA has been installed, I recommend deactivating the PPA afterwards....
