If the system contains software packages such as-Dev, we recommend that you use the following dselect Operation Method to refine the control software package.
# Dselect update # complete this step before Upgrade
# Dselect select # select additional software package
When running dselect, all current software packages are selected. dselect will prompt you to add additional software packages based on depends, suggests, and recommends. If you do not want to add any software packages, just enter Q to exit dselect.
# Dselect install
During installation, you must answer some questions about the software package configuration and prepare your notebook to take some time to handle them.
