[ubuntu-za] Updating Without a Local Connection

[James Cuénod]

Hi all,

I am running Kubuntu 8.10 64 bit on my laptop. I am at varsity right now
and am not allowed to connect my laptop to their network (because the
lecturers' PCs are all on it). I know that an update script can be
generated using synaptic (which, strangely, came by default with my
install - along with adept which I am not too fond of). So my question is
two fold;

1. How can I update my sources.list
2. Does anyone have any words of wisdom regarding generating the update
script with synaptic. Thanks

Also, I would prefer it if answers were not links to websites because this
email is free but I have to pay if I want to surf...

Much appreciated.
