The Operating system is the most essential part of a computer system. Operating system vendors periodically release updates to increase their performance and add new functions. In Ubuntu Linux you can use apt-get for complete up-gradation. Apt-get is a powerful command line utility, which is used to communicate with Advanced Packaging Tool (APT) of Ubuntu. It performs installation of new applications packages, update package list index, and upgrade existing software packages. It can even upgrade the core Ubuntu operating system files. Apt-get upgrade checks all software packages in system and then checks those software packages that could be upgraded without uninstalling or affecting anything in the operating system. Then it installs the upgrades. Ultimately you have a fully upgraded Linux system and the software packages that could not upgrade automatically. Being a straightforward command line utility, apt-get has a number of benefits over other application package manag ement toos available for Ubuntu server administrators. Some of the key benefits of this upgrade include: Ease of use as compared to the Simple Terminal Connections (SSH) Compatible with system administration scripts Automated upgrade using the cron (short for chronograph) scheduling toolAlthough, apt-get is an extremely useful tool for Ubuntu up-gradation, but sometimes it may lead to problems.
