[ubuntu-uk] Kroning Updates

[Ian Pascoe]

Hi all

I'm looking to provide my eldest daughter with a laptop as she will shortly
be moving into secondary education.  I don't want to necessarily provide her
with full admin rights to her machine, but my only qualm is that of keeping
it updated.

How can I set up a kron job or similar that will automatically update the
machine without the necessity of her either using Update Manager or the
terminal?

Ideally so that it runs weekly.

Thanks

E
