You may have issues because of your location, but you can check via synaptic (sorry I don't know how to do this outside of synaptic. So open the terminal and : $ sudo apt-get install synaptic $ gksu synaptic Once synaptic opens, click 'Settings|Repositories|Ubuntu Software|Download from... Other|China' and select another server. You can also click on 'Select Best Server' and allow synaptic to go out & test which mirror/server is fastest for your location. Then when you return to 'Ubuntu Software' select 'Close' and then 'Reload' and try again. -- ubuntu-users mailing list <a href="mailto:ubuntu-users@lists.ubuntu.com">ubuntu-users@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-users" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-users</a> </blockquote></div> -- William Herry ==================== WilliamHerryChina@Gmail.com
