Ubuntu in an educational institution

Some time ago I found out that in one educational institution in St. Petersburg a computer class room stands idle due to the fact that there is no licensed OS. When I said that there are OSes that are free and are not inferior to the usual Windows, they looked at me as if they were a charlatan. However, a few days later I showed up with a couple livevsdies in my backpack and so this small event started.

Choose between Ubuntu and Kubuntu (version 9.10). Gnome liked more. Yes, I forgot to say what the initial conditions in this problem. And the initial conditions are as follows:

• 20 computers
• Celeron D 2GHz, RAM 256 Mb
• lack of internet access
• narrow special subjects

Actually in the first visit, the system was installed on several computers for review. The next problem was to somehow update the system. I set up the system at home in a virtual machine and wanted to restore it there, and then somehow create a repository and update all the other machines on the network. This plan has failed. As a result, I had an iota and I was able to bring the teacher’s computer to mind. Only later he put apt-proxy on it, but he could not use it (because he hasn’t saved anything yet), but the rest of them see their new update server. Actually, with the help of aptoncd today updated the other computers manually.

I needed a system that could answer the following:

1. Student records
2. Evaluation for work
3. Test items
4. Educational materials
5. The ability to create a variety of tests without third-party help, etc.

In all respects, the moodle system came up, which, in fact, my comrade advised me, and I read it on the Internet, and I agreed.

Actually, what we have at the moment: a computer class with fully Russified Ubuntu , a low-tuned moodle and an immense amount of desire to bring it all to mind.

In conclusion, many will probably ask why I wrote all this. Firstly, my knowledge is very limited and I would be happy for advice that could facilitate the implementation of this idea. Secondly, I am interested in the promotion and development of free technologies. And, of course, I just wanted to share.
