{{blue|'''Installing'''}} a package '''from REPOSITORIES''', using '''aptitude''':

''Note: Advantage of <code>aptitude</code> over <code>apt-get</code> is that it maintains <tt>/var/log/aptitude</tt>, and remove dependencies by default.''

{{blue|'''Querying'''}} the '''cache''' or '''installed''' packages:

==== APT with several releases ====

Content of file <tt>/etc/apt/apt.conf.d/00default</tt> (or <tt>/etc/apt/apt.conf</tt> if that file doesn't exist):
<source lang="bash">
APT::Default-Release "testing";
</source>

This changes the order of preference for packages. Here it says <tt>default=testing=wheezy</tt>, so:

<source lang="bash">
$ apt-cache policy virtualbox-osevirtualbox-ose:
Installed: (none)
Candidate: 4.0.2-dfsg-1
Version table:
4.0.4-dfsg-1+b1 0
500 http://ftp.be.debian.org/debian/ sid/main amd64 Packages
4.0.2-dfsg-1 0
990 http://ftp.be.debian.org/debian/ wheezy/main amd64 Packages
3.2.10-dfsg-1 0
500 http://ftp.be.debian.org/debian/ squeeze/main amd64 Packages
</source>
The number (500 vs 990) is giving the priority.

Ubuntu / Debian

See apt.

RPM's

rpm -ivh package                    # Installing a package - verbose and progress bars
rpm -iv -nodeps package             # Installing a package (verbose), ignore dependencies
  • Query commands
rpm -ql package                     # List files provided by a package
  • To query a package that has not been installed, add -p option to the command:
rpm -qpl package                    # List files provided by a package

Source package

Installing from source package is usually done with 

./configure
make
sudo make install

Usually ./configure --help gives additional package configuration options (like installing documentation, etc).

Installing build dependencies
Building from sources usually requires more dependencies than using the package. If the package is available on the distribution, the easiest way to install these dependencies is usually via apt-get build-dep:
sudo apt-get build-dep udisks
Installing as a package
Instead of installing with make install, use checkinstall to create a temporary package that can later be uninstalled with the package manager.
./configure
make
sudo checkinstall                  # Creates a package and install it as if 'sudo make install' was run

#... to uninstall:
sudo dpkg -r <packagename>
Note that checkinstall can actually run any arbitrary command and monitor change on the file system.

Backports

Debian

See Backporting Debian packages.
