apt-get: Hash Sum mismatch

Hi All,

So, sometimes, just when you think that apt-cacher-ng is your amazing solution, or you have managed to get apt-get going through a proxy, you get hit by something like this:

Failed to fetch http://gb.archive.ubuntu.com/ubuntu/dists/lucid-updates/main/source/Sources.bz2 Hash Sum mismatch

That's no good is it? You try wget and that works fine, but apt just will not work. Here's how to fix it. Unfortunately I don't know what causes it. For me it has worked for ages and just broke one day and refused to work. Try the following (run as root):

touch /etc/apt/apt.conf.d/no-cache
nano /etc/apt/apt.conf.d/no-cache

type this line in and save it:

Acquire::http {No-Cache=True;};

The run:

apt-get update

This should now work with no problems.

Thanks for reading.
