These are not installed with an upgrade, as this command only updates the packages you already have installed.The kernel and firmware are installed as a Debian package, and so will also get updates when using the procedure above.But why get the Software Center at all, if the goal is to install updates via the command line?(None of the subsequent commands you recommend require the Software Center, nor do any of them use it or benefit from it if it's installed.) Note also that it seems unlikely this will keep the "packages can be updated" message from appearing. 'dist-upgrade' in addition to performing the function of upgrade, also intelligently handles changing dependencies with new versions of packages; apt-get has a "smart" conflict resolution system, and it will attempt to upgrade the most important packages at the expense of less important ones if necessary.
Before anything is deleted, you will have to confirm that you wish the action to take place by typing “Y.” After you confirmed it the applications are removed from the server.Would you like to answer one of these unanswered questions instead?dist-upgrade dist-upgrade in addition to performing the function of upgrade, also intelligently handles changing dependencies with new versions of packages; apt-get has a "smart" conflict resolution system, and it will attempt to upgrade the most important packages at the expense of less important ones if necessary.It is recommended that you regularly update your package list for security and server performance.Many years ago, when I first began with Linux, installing applications and keeping a system up to date was not an easy feat.However, the server administrator needs to know when upgrades are available, which of them are security updates, how urgent is an upgrade, and if system reboot is required after system update. This how-to is also applicable to Ubuntu (or other Debian based Linux distributions). Our recommendation is apticron report [Sun, 0200] ======================================================================== apticron has detected that some packages need upgrading on: cosmos.[ 127.0.0.1 95.2 95.2 ] The following packages are currently pending an upgrade: perl 5.10.1-17squeeze6 perl-base 5.10.1-17squeeze6 perl-modules 5.10.1-17squeeze6 sudo 1.7.4p4-2.squeeze.4 ======================================================================== Package Details: Reading changelogs...--- Changes for sudo --- sudo (1.7.4p4-2.squeeze.4) stable-security; urgency=high * Fix cve-2013-1775: authentication bypass when the clock is set to the UNIX epoch [ UTC on 1 January 1970] (closes: #701838).In fact, if you wanted to tackle either task you were bound for the command line.For some new users this left their machines outdated or without applications they needed. Now Linux is exponentially more user friendly - to the point where so much is automatic and ¬†that today's Linux hardly resembles yesterday's Linux.The Advanced Package Tool, or APT, is the user interface that works on your server to handle the installation and removal of software. If you do not have any files on your server, it is recommended to use apt-get or apt to install an application.Apt does not need to know the file name since it uses the file extension instead of the file name.
