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
