drakrpm-edit-media First thing to do after an install is to add software sources (also known as repositories, media, mirrors). That means you must select the media sources to be used to install and update packages and applications. (see Add button below). If you install (or upgrade) Mageia using an optical media (DVD or CD) or a USB device, there will be a software source configured to the optical media used. To avoid being asked to insert the media when you install new packages, you should disable (or delete) this media.  (It will have the media type CD-Rom). Your system is running under an architecture which may be 32-bit (called i586), or 64-bit (called x86_64). Some packages are independent of whether your system is 32-bit or 64-bit; these are called noarch packages. They don't have their own noarch directories on the mirrors, but are all in both the i586 and the x86_64 media. This tool is present in the Mageia Control Center under the tab Software management. U kunt deze tool op de commandoregel starten, door als root drakrpm-edit-media te typen.

Column Enable: The checked media will be used to install new packages. Be cautious with some media such as Testing and Debug, they could make your system unusable. Column Update: The checked media will be used to update packages, it must be enabled. Only media with "Update" in its name should be selected. For security reasons, this column isn't modifiable in this tool, you must open a console as root and type drakrpm-edit-media --expert. Column medium: Display the medium name. Mageia official repositories for final release versions contain at least: Core which contains most programs available supported by Mageia. Nonfree which contains some programs which are not free Tainted free software for which there might be patent claims in some countries. Each medium has 4 sub-sections: Release the packages as of the day the this version of Mageia was released. Updates the packages updated since release due to security or bug concerns. Everyone should have this medium enabled, even with a very slow internet connection. Backports some packages of new versions backported from Cauldron (the next version under development). Testing which is used for temporary tests of new updates, to allow the bug reporters and the QA team to validate the corrections.

Remove: To remove a medium, click on it and then on this button. It is wise to remove the medium used for the installation (CD or DVD for example) since all the packages it contains are in the official Core release medium. Edit: Allows you to modify the selected medium settings, (URL, downloader and proxy). Add: Add the official repositories available on the Internet. These repositories contain only safe and well tested software. Clicking on the "Add" button adds the mirrorlist to your configuration, it is designed to make sure that you install and update from a mirror close to you. If you prefer to choose a specific mirror, then add it by choosing "Add a specific media mirror" from the drop-down "File" menu. Up and down arrows: Change the list order. When Drakrpm looks for a package, it reads the list in the displayed order and will install the first package found for the same release number - in the event of a version mismatch, the latest release will be installed. So if possible, put the fastest repositories at the top.

File -> Update: A window pops up with the media list. Select the ones you want to update and click on the Update button. File -> Add a specific media mirror: Suppose you aren't happy with the actual mirror, because for example it's too slow or often unavailable, you can choose another mirror. Select all the actual media and click on Remove to take them out. Click on File -> Add a specific media mirror, choose between update only or the full set (if you do not know, choose the Full set of sources) and accept the contact by clicking on Yes. This window opens: You can see, on the left, a list of countries, choose yours or one very close by clicking on the > symbol, this will display all the available mirrors in that country. Select one and click on OK. File -> Add a custom medium: It is possible to install a new media (from a third party for example) that isn't supported by Mageia. A new window appears: Select the medium type, find a smart name that well define the medium and give the URL (or the path, according to the medium type) Options -> Global options: This item allows you to choose when to "Verify RPMs to be installed" (always or never), the download program (curl, wget or aria2) and to define the download policy for information about the packages (on demand -by default-, update only, always or never). Options -> Manage keys: To guarantee a high level of security, digital keys are used to authenticate the media. It is possible for each medium to allow or disallow a key. In the window that appear, select a medium and then click on Add to allow a new key or to select a key and click on Remove to disallow that key. Do this with care, as with all security-related questions Options -> Proxy: If you need to use a proxy server for internet access, you can configure it here. You only need to give the Proxy hostname and if necessary a Username and Password. For more information about configuring the media, see the Mageia Wiki page.
