A few words about application sources (sources.list)

application sources

In the second video, we have already opened this window by selecting “System” – “Administration” – “Application Sources“. By the way, now the videos will be uploaded mainly on vimeo.com , because in my subjective opinion, this is the best video hosting at the moment in terms of quality.

So, at the expense of application sources. While it is not possible to record voice comments on the video, I will try to describe it in text. But you can’t remember everything …

So, on the first tab, we see the settings for the Ubuntu software downloaded over the Internet. Actually, I already said about the disk that you can turn it off if it makes it unnerving to insert it every time. But in the “Download from” field, you can select the “Other …” item, and a window will appear before our eyes, where Russia is represented by three servers: ftp.chg.ru , ftp.mipt.ru and mirror.yandex.ru . It is not difficult to guess what kind of server they are. If you are firmly convinced that one of them is closer to you than others, choose one, although it may be slower than others. Nevertheless, you always have the opportunity to return everything as it was …

In general , this action will affect where exactly updates and installation packages for all software will be downloaded, except for the “security” branch, which will remain tied to the security.ubuntu.com server .

The second tab is called Third Party Software. As the name implies, here we will collect links to servers that allow us to conveniently and safely download the applications we need. Servers are added as a string, for example:

deb http://archive.ubuntu.com/ubuntu/ gutsy main

This line contains a space separated: type, link, distribution, components. I think we will turn to this window more than once …

The third tab that interests us today is updates. In general , you cannot say much here, the window allows you to configure the type and frequency of checking for updates. In the video, I have not marked the “gutsy-proposed” and “gutsy-backports” items. Not that something terrible will happen if you mark them, on the contrary, we will receive all the newest updates. But, on the other hand, we want our system to work stably. So in the first couples, we will probably do without these two checkboxes, and then we’ll see …

Finally, it is worth noting that the data of all three bookmarks that we have now examined is stored in a file /etc/apt/sources.list. There you can forcibly replace all servers by specifying, for example, servers inside the local network, which will allow you to update without going online. Almost all large local area networks have such servers. But remember, always create a backup before editing anything .
