You can also select or deselect all packages listed within a particular group, by clicking on the Select
all in group
or Unselect all in group
buttons.
Note
Some packages (such as the kernel and certain libraries) are required for ev-
ery Red Hat Linux system and are not available to select or deselect. These
base packages are selected by default.
3.18.2 Unresolved Dependencies
Many software packages, in order to work correctly, depend on other software packages that must be
installed on your system. For example, many of the graphical Red Hat system administration tools
require the python and pythonlib packages. To make sure your system has all the packages it
needs in order to be fully functional, Red Hat Linux checks these package dependencies each time
you install or remove software packages.
If any package requires another package which you have not selected to install, the program presents a
list of these unresolved dependencies and gives you the opportunity to resolve them (see Figure 3–18,
Unresolved Dependencies).
The
Unresolved Dependencies screen appears only if you are missing packages that are needed by
the packages you have selected. At the bottom of the screen, under the list of missing packages, an
Install packages to satisfy dependencies checkbox is selected by default. If you leave this checked,
the installation program will resolve package dependencies automatically by adding all required pack-
ages to the list of selected packages.
