I'm currently running 14.04 x64, and for the last few days, running either System Updater or apt-get update results in very long wait times (one of the last tries clocked in at over 14 minutes) until the new available packages are ready to be installed (and that's before download even starts).
From what I could tell, it seems that one or more of Canonical repos have either a huge reply time, or just a fantastically slow transfer speed. One of the last "hung" replies seemed to be a particular IPv6 address for security.ubuntu.com (my ISP offers IPv6 networking).
Can anyone provide any insight on what might be going on, and how to make it work swiftly again?
For reference, I'm subscribing to the Portugal main, universe, restricted, and multiverse sources, as well as the following ppas:
Hardware-wise, I'm running a basic Intel CPU+mobo combo, no dedicated GPU or any odd piece of kit. Software-wise, it's pretty much standard, AFAIK, except for a couple of Cloud apps (DropBox and CloudPT).
Any help would be very much appreciated.
Thanks in advance for any help you guys can give me.
P.S.: I'm a Linux newbie, so please don't assume I'll know what you're talking about. My knowledge is fairly limited, I'm still adjusting from Windows.
