apt-get install python2.2-xmlbase - unmet dependency

[Herbert Straub]

I try to install the package python2.2-xmlbase, but i get the following error:

sudo apt-get install python2.2-xmlbase
Reading Package Lists... Done
Building Dependency Tree... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
  python2.2-xmlbase: Depends: python2.2 (= 2.2.3-10) but 2.2.3-10ubuntu0.1 is to
be installed
E: Broken packages


The python2.2-xmlbase is from the universe archiv, but the required versions are
the same: python2.2 (=2.2.3-10) and 2.2.3-10ubuntu0.1. The only difference is
the suffix ubuntu0.1.

What can be done is such circumstances? apt-get source and change in the control
file the dependency string to 2.2.3-10ubuntu0.1 or better to >=2.2.3-10
