Apt, Software and Package Basics

Here is some basic information on how to use the Apt package management tools.

  • Installing packages
sudo aptitude install <packagename>

Examples:

sudo aptitude install mpd sbackup
  • Removing packages
sudo aptitude remove <packagename>

Examples:

sudo aptitude remove mpd sbackup
  • Searching for packages
sudo aptitude search <keywords>

Examples:

sudo aptitude search Music MP3
sudo aptitude search "Text Editor"
  • Updating Apt database (used after adding/removing Apt repositories)
sudo aptitude update
  • Upgrading packages
sudo aptitude upgrade
  • Upgrade entire distribution
sudo aptitude dist-upgrade
  • Install downloaded Ubuntu (Debian) package (.deb)
sudo dpkg -i package.deb
  • Remove Ubuntu (Debian) package
sudo dpkg -r package
  • Reconfigure/Repair installed package
sudo dpkg-reconfigure package

Examples:

sudo dpkg-reconfigure mpd
  • Handling ".tar.gz" (Tar/GZip) Archives

To extract:

tar xvzf package.tar.gz

To create:

tar cvfz package.tar.gz folder
  • Handling ".tar.bz" (Tar/BZip) Archives

To extract:

tar xvjf package.tar.bz

To create:

tar cvjf package.tar.bz folder
  • Extracting ".bz" Archives
bunzip2 file.bz
  • Extracting ".gz" Archives
gunzip file.gz
  • Building from Source

Make sure you have all the neccesary development tools (i.e. libraries, compilers, headers)

sudo aptitude install build-essential
sudo aptitude install linux-headers-`uname -r`

Extract your package (as detailed above)

tar xvzf package.tar.gz

Commence the build process

cd /path/to/extracted/package
./configure
make
make install

If build is successful, consider making an Ubuntu (Debian) package (.deb) for future use:

Install package tools:

sudo aptitude install checkinstall

Rebuild package using "checkinstall":

cd /path/to/extracted/package
./configure
make
checkinstall

Keep the resulting ".deb" file for future use. It can be installed using:

sudo dpkg -i package.deb

Note: These are basic instructions that may not always work. Some packages require additional dependencies and optional parameters to be specified in order to build them successfully.
