Help: Edit package sources

Information

Software packages can be installed from different sources (HTTP,FTP,CDRom etc.). Different sources are needed, if not all of the software packages can be installed from the same medium. To make it easy for you to administrate these package sources, you can enter them as expected by your selected distribution.

• Loading a package source: Select a package source from the list (top/right) and click on "Load". The package source will be loaded in the editor.
• Deletion a package source: To delete the package source loaded in the editor, click on the "Delete" button and accept your decision in the next dialog.
• Saving a package source: The system will always save the package source loaded in the editor. It doesn't matter which package source is selected in the list. After you have selected a distribution, it is possible that you need to specify your choice. Choose a user interface from the list displayed under the editor and select the architecture(s) supported by the package sources list under "Architecture". Think about a good name for your package source and enter it below "Package source name". If you have loaded a package source before, the package source name is written into the field "Package source name" automatically. If you want, you can enter a comment into the "Description" text field. Afterwards, click on the "Save" button.
• Test the package source: After entering a package source list, you should test if all sources are working properly. Simply click on the "Test" button. The package description files will be downloaded and a test report will be shown thereafter. It can take minutes until the report is shown, depending on your internet connection speed and the speed of the used software package servers.
• Select Mirror: If you would like to use a different mirror (the standard server is ftp.debian.org) for the installation of the base system, enter it as follows in a new line of your package source: #mirror: [URL to the packages]. URL to the packages describes the protocol, the hostname or the IP and the directory that contains the packages. A valid URL may look like this: #mirror: http://192.168.7.14/debianCDs.
• Create configuration files: Every package sources list offers the option to create additional files (e.g. for package manager configuration). For every file you wish to add, add a new line following this syntax:

  #addToFile:[file name with full path to file]###[1. line]###[2. line].

  Replace Ersetzen Sie hierbei "[file name with full path to file]" by the correct value (e.g. /etc/apt/preferences). The lines in the output file from the package sources list will be separated by three hash signs (###) instead of linebreaks, as the command to creat a file must be given in a single line.

• Supported file systems: Every distribution offers support for a number of file systems. These can vary from distribution to distribution. Please list the supported file systems in a separate line:

  #supportedFS: [file system 1], [file system 2], [file system 3]

  Each line can contain any number of file systems (separated by comma and space) (e.g. #supportedFS: ext2, ext3, ext4, reiserfs).

  If you select an unsupported file system when formatting a client, the file system will automatically be adapted to one that is supported when the formatting process starts. This fallback file system must be indicated with the line

  #alternativeFS: [file system] (e.g. #alternativeFS: ext3).

Hint

• If you save a package source under a name that already exists, the old package source will be overwritten with the contents of the editor.
• Benutzeroberflächen sind direkt an eine Paketquellenliste gebunden. D.h. wenn Sie eine bestimmte Paketquellenliste für einen Client benutzen, können Sie nur die Benutzeroberflächen verwenden, die Sie in diesem Dialog für die Paketquellenliste freigeschaltet haben. Sie sollten hier deshalb nur die Benutzeroberflächen auswählen, die garantiert von den Paketquellen unterstützt werden.
