Now we have got the Ubuntu operating
system installed on our PC. So now if we want to install packages we
can do it from Synaptic package manager but we can also do it from
the Terminal too. So let us learn the basics of doing it in this
article.
To install packages:
sudo apt-get install packagename
For example:
sudo apt-get install mpd sbackup
To remove packages:
sudo apt-get remove packagename
To remove all dependencies:
sudo apt-get autoremove
For example:
sudo apt-get remove mpd sbackup
To search for packages:
apt-cache search <keywords>
For example:
apt-cache search Music MP3
apt-cache search "Text Editor"
To update the apt package database
after adding/removing repositories:
sudo apt-get update
To upgrade packages:
sudo apt-get upgrade
To upgrade the entire distribution
(e.g. from Maverick to Natty):
sudo apt-get dist-upgrade
Now we will learn how to install .deb
packages from the Terminal
To install a downloaded Debian (Ubuntu)
package (.deb):
sudo dpkg -i packagename.deb
To remove a Debian (Ubuntu) package
(.deb):
sudo dpkg -r packagename
To reconfigure/Repair an installed
Debian (Ubuntu) package (.deb):
sudo dpkg-reconfigure packagename
Now we have seen installing packages
and every thing with the help of apt-get from the Terminal. There is
another one which can replace it. That is Aptitude. Aptitude is a
terminal-based package manager. It marks the packages that are
automatically installed and removes them when no packages depend on
them. So this is a best and feature present in Aptitude. So to use
this replace apt-get with Aptitude through the terminal. Now let us
see how to use it in brief.
sudo aptitude install packagename
sudo aptitude remove packagename
sudo aptitude update
sudo aptitude upgrade
For an ncurses-based graphical user
interface, type:
sudo aptitude
For more information about using
Aptitude use the Aptitude documentation from It's official web site.
