Apt-cacher and Apt-proxy

Solution 1:

Use approx. I had continuous issues with apt-proxy, switching to approx solved all my problems.

Solution 2:

If you read both of these you should be able to figure out the difference.

apt-proxy

apt-cacher

The apt-proxy is used to get packages from a remote machine. The apt-cacher is used to create a local proxy for packages.

Solution 3:

I have used mod-proxy in apache to provide this service in the past. With proxy-cache, it seemed to work better than either of these solutions.

Squid with a cache may also do. There are the squid-deb-proxy package for caching, with squid-deb-proxy-client for cac autodiscovery of the cache.
