It happens to me too.

0.7.4ubuntu5 also

Confirmed here also.

There is no need to "confirm" a bug more than once.

Same for python-apt 0.7.4ubuntu5 on hardy for x86

Workaround : After installing python2.4, here is the output :

Paramétrage de python-apt (0.7.4ubuntu5) ...
'import site' failed; use -v for traceback

Paramétrage de update-manager-core (1:0.87.8) ...
'import site' failed; use -v for traceback

So python-apt is now updated, but with a "'import site' failed; use -v for traceback" error.

I suspect this fixes this and other related issues:

python-central (0.5.50ubuntu5) hardy; urgency=low

  * do not crash if a package has private files

You might want to run `apt-get -f install' to correct these.
The following packages have unmet dependencies:
  python-apt: Depends: libapt-inst-libc6.6-6-1.1 but it is not installable
              Depends: libapt-pkg-libc6.6-6-4.5 but it is not installable
E: Unmet dependencies. Try using -f.
