It seems I download realatively slowly from Ubuntu's main download server, and I wanted to change the location. I've been reinstalling frequently, and installs are painfully slow (talking speeds less than 50KB/s; I think I even seen bytes/s a few times) because of the slow downloads; especially during the language pack downloads.
I know I can download updates faster from other mirrors, but afaik, I can only change where I download the updates from after the OS install. Can I change where the installer itself downloads the language packs and everything else it needs?
I use 14.04 also if it matter.
