Workstation Update Management
Wednesday, March 08, 2006
PCQLinux has a large number of software packages that make
up the distribution. Also each of these packages have a ton of dependencies that
need to be resolved before it can be installed. And when it comes to updating a
package and its dependencies, it is a different matter altogether in terms of
complexity. For a network, the system administrator should setup a package and
dependency download server that acts as an update server.
However, if yours is the only such machine you need to be
able to manage the installed packages yourself. And this is where a graphical
package manager like Synaptic really helps. We use Synaptic as the update
manager for PCQLinux 2006.

Managing installed packages
When you start up Synaptic, you will see a list of packages that are
installed and available on your system. You can manage this list by sorting,
searching and filtering them.
Once you have selected the package you are interested in, a
bried description of the package is shown. You can then decide whether to
upgrade, reinstall or delete this package. In the case of a delete, Synaptic
will warn you if there are any other packages which depend on this particular
one.
Installing packages
To install a package, simply select the .deb or .rpm file and it will work
out the dependencies for it. If it finds the dependencies in any of the
registered repositories, it will also install these in the correct order to.
Adding Repositories
You can add more repositories from where to pick up updated and new
application packages as well as do automatic dependency resolving. For this,
select Settings | Repositories | New. Enter the required URL of the repository
and other details and save it.
Once this is done, click the 'Reload' button to get the
online repository list as well as the locally installed package with version
listing.
Using the different search filters, you can upgrade
individual packages, the full system or install new packages from the
repositories.
