Inspect the output of

$ apt-cache show linux-image-2.6.18-5-486 --no-all-versions

and

$ wget --spider \
http://security.debian.org/pool/updates/main/l/linux-2.6/linux-image-2.6.18-5-486_2.6.18.dfsg.1-13etch4_i386.deb

Compare the "Size" field of apt-cache output with the "Length" field of 
wget output. They should match. (they do on my system)

If you get different sizes, then delete all the cached package lists in 
/var/lib/apt/lists, run apt-get update and apt-get dist-upgrade again to 
see if it fixes the problem
