house over the weekend to resurrect apt-zeroconf: http://castrojo.wordpress.com/2009/06/27/resurrecting-apt-zeroconf/Something like apt-zeroconfig would be very helpful to spread the bandwidth around. However there is one use case that it doesn't solve, which is cases where someone has 1 (or 10) computers in location A (eg a school they work in), and there is one internet café in the town that has internetaccess. The only connection those computers have to the internet is oversneakernet.
Agreed, that's important. Putting packages onto CD for installation elsewhere is also mentioned on the ubuntu ngo wiki pages.
Suppose I have an Ubuntu installation (without internet) that I want to update. How would this work, and how user friendly is it?
Here's a scenario: Could you somehow write the state of a particular Ubuntu installation to a 'config' file, where this file would contain the versions of all your packages? Then, you take this file with you, to a place with good bandwidth, and download all the updates you need?
To make this very usable, perhaps there could be package manager like application (an "offline package manager"), that doesn't work with the system packages, but works with such a config file instead? I.e. it first writes the config file, and later (on a different computer) lets you load up the config file again, to see what updates are available, and what other applications you can install. All those are not installed, but downloaded instead, and can be burnt to disk, ready for installation. (Ideally with a handy installer program, perhaps via the same "offline package manager").
There may of course already be a similar system available that I don't know about :-) Any suggestions?
All the best, Bjoern
