Andy, everybody,

Righto - I didn't realise that it fetches the files "real time" for
the first time. Quite natural now when mentioned.

Thanks for explaining! I'm very new to, but intrigued by, VPS'. :)
So, a shutdown -h in terminal and then a power-up in Zen console. Check!

On a normal machine with grub, a reboot gets you to the point where
the BIOS runs grub and grub gets kernel, initrd, etc.
On a Xen domU with pygrub, on domain creation pygrub runs in dom0
(the host server) to read your filesystem, extract your grub config
file, parse it to find the kernel, initrd etc., extract *those* to
a temporary directory and then create a domU with those files.
But on a reboot, Xen never actually destroys the virtual machine, it
just starts it again. That means it will have the same kernel
(pygrub is never run), same amount of RAM, most probably the same
size disk devices as well (I have never tested that bit). Don't forget that you need to shut down and
boot again from xen
shell in order to get a new kernel; just rebooting uses the same
kernel again.
Why is this? I thought that, at least on Ubuntu a 'shutdown -r'
picks up
the latest kernel?! Get:13

Both of them are stuck around 45% download...
The apt-cacher will proxy a connection to the real Ubuntu mirrors if
it doesn't have the file locally, so it could be that the mirrors
are overloaded. Is it still happening?
As of a few seconds ago, yes. Still happening.
My unqualified guess would be that this file has been half-downloaded
by the cacher..?!
Can you try other mirrors (change the part of the URL
that is the
mirror hostname)?
Such as to http://gb.archive.ubuntu.com/ instead of http://apt-cacher.lon.bitfolk.com
?
I can yes. I am, however, a bit reluctant to mess with live servers.
If it's what it takes to get things going, then naturally I'm up for it.
