On the Raspberry Pi (Raspbian image) there are three files you will need to edit: /etc/apt/sources.list I went for option two as it makes things more transparent to the user (student) how things are configured. According to the documentation you have two options add an environment variable to apt on the client or edit each apt sources file to direct it through the caching server. You do now need to configure your clients however. There you now have an Apt-Cacher server installed easy wasn’t it! Have an exception put in your firewall to allow this IP address access to port 80 and 443 and set your proxy server to ignore any traffic from this IP address too.Assign your new server a static IP address and internal DNS address etc.Our production server only has a 50 Gb HDD and is only using 25% of that)

Install a Ubuntu server (it doesn’t need much RAM – 1 Gb will do.For more detail visit the very good documentation.
I shall not go into great detail about installing Apt-Cacher NG as it “just works”, however here are some very basic steps to configure it. All other servers can access the apt repositories via the local network! So what are the benefits of installing this server? It will mean that your firewall need only allow one server (the caching server) direct access to the Internet. The main difference between the two is that Apt-Cacher NG handles apt repositories from multiple distributions without any additional configuration Apt-Cacher does not. The are two apt caching servers available to you: Apt-Cacher and Apt-Cacher NG. This sits between your local servers and the Internet and intercepts the apt requests and proxies them through itself, storing a cached version of the package to serve to the next server which requests it. The second option is to set up an apt cache server. Now this was an option to me again but it is one which takes a considerable amount of local storage as you have to store all the packages on your local apt repository. It is possible to configure apt-get in Debian to make use of an authenticating proxy server to access the Internet but I have never been successful in doing so.Īs I began to bring up more Ubuntu Linux servers at school, I became less happy about allowing all of these servers to have direct outgoing access to the Internet (ports 80 and 443) through the firewall, so began to look for other alternatives.Īt my previous school we had bought up a Ubuntu Server which acted as a local apt repository of all the packages we wanted access to on our local servers.
Raspberry pi sudo apt get update all software#
Now all derivatives of Debian have this in common they use apt (or aptitude) to install, update and manage their installed software packages. The Raspberry Pi ( running the Raspbian OS) is in essence a stripped down version of Debian Linux as is Ubuntu. Now if your school network is similar to mine it will make use of a proxy server for Internet access which will probably also require some form of authentication which is more than likely to be tied into the school’s Internet filtering. It actually leverages something that I put in place for our Ubuntu Linux servers, but works just as well for Raspberry Pi devices too. I have seen many posts on both Twitter and CAS about teachers having issues getting their class Raspberry Pis to update and install software through their school firewalls, so I thought I would share the simple solution that I have implemented at my school.
