Size Mismatch on Debian 7.6.2

[ChrisNY]

I am trying to upgrade from 7.5.5 to 7.6.2 using the testing repo. When I run apt-get upgrade I get the following message:
Failed to fetch http://debian.slimdevices.com/pool/m...~33593_all.deb Size mismatch

Anyone have any tips? I'd like to get upgraded to 7.6.2 while it's still available through the repos. I am using Ubuntu Lucid (10.04).

Thanks!

try adding:

74.115.217.0 debian.slimdevices.com

to your /etc/hosts file.

This points the repository at the source machine, and avoids problems with out of date mirrors.
