Thousands of programs are freely available to install on Kubuntu. These programs are stored in software archives (repositories) and are made available for installation over the Internet. This makes it easy to install new programs in Kubuntu. It is also secure, because each program is built specifically for Kubuntu and is checked thoroughly before it is installed. Kubuntu repositories are categorized into four groups:
Main
Restricted
Universe
Multiverse
Two factors are used to determine categories:
The level of support that software development teams provide for a program
The level of compliance the program has to the Free Software Philosophy
More information about the Repositories is available on the Ubuntu website.
The standard Kubuntu LiveCD contains some software from the Main and Restricted categories. Once a system has information about the Internet-based locations for these repositories, more programs are available for installation. Using the software package management tools installed by default, it is possible to discover, install and update any piece of software directly over the Internet, without the need for the LiveCD.
To enable extra repositories:
Start Software Center by choosing → → .
Select → in the Software Center package manager window.
Для продолжения требуется пароль админстратора.
Затем выберите закладку Другие программы. Существующие репозитарии могут быть включены или выключены установкой соответствующих флажков. Для добавления новых репозитариев нажмите кнопку Добавить.
Enter the repository address. The proper format is required, and looks similar to this:
deb http://ppa.launchpad.net/kubuntu-ppa/backports/ubuntu oneiric main
After adding the repository, a prompt will appear to update the package list. This will allow Muon to find the newly available software.
Для удаления репозитария нужно выбрать необходимые пункты в списке Источники программ и нажать кнопку . После завершения операции можно нажать кнопку для выхода.
