Ubuntu: no upgrade for 2 weeks


I've been using ubuntu for 2 years now. And every 1 or 2 days I had something to upgrade. But today it's been maybe 2 or 3 weeks since the system detected the last upgrade to do. I think something goes wrong with my Xubuntu.

What I did :
1/ in synaptic I chose the repositories : Main , universe
And I chose the "Main server" to download from.

2/ then in a terminal :

sudo apt-get update  sudo apt-get upgrade  

and I always have 0 new package to install ... Do you have the same "trouble" ? It's very strange. Thanks for your help


If the version you installed 2 years ago is not listed here (11.04 for example), it is no longer supported and you should update to a newer release of Ubuntu.

To find your version of Ubuntu, press Ctrl + Alt + T and type lsb_release -a then Enter

My version was 12.04 so still supported. Finally I had found the trouble:

In Synaptic â†' Settings â†' Repositories â†' Updates nothing was ticked. So I ticked "Important Security Updates" and "Recommended Updates". Then updates worked again normally. :)

But I really don't know why they were "un-ticked". This is quite strange.
