Debian Install failure: Hash Sum Mismatch

I've just got hold of a new (to me) 2 gig card that Debian fails to
install on at almost the same point. I thought it might be a problem
related with the anti-virus on our firewall getting a hammering, so I
whitelisted the debian mirror and tried again, but it fails as before.
I've downloaded a couple of packages and md5sum'ed them - the returned
sums are correct, although I'm not going to go to the hassle of
manually downloading all the packages that failed and copying them
local to my phone.

Anyone have any more ideas?


>how very anti-climactic

It's even worse if you're actually there...
