[sisyphus] apt не ставится

[Oleg Sukhanov]

Некоторое время не обновлял систему. Решил сделать точечное
обновление, а не получается:

[root на r01 /]# apt-get install apt

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:
  apt: Depends: libapt (= 0.5.15cnc6-alt17) but 0.5.15cnc6-alt4
is to be installed
       Depends: libapt-pkg-libc6.3-6.so.0
       Depends: libstdc++.so.6
       Depends: libstdc++.so.6(CXXABI_1.3)
       Depends: libstdc++.so.6(GLIBCXX_3.4)
E: Broken packages
[root на r01 /]# apt-get install apt libstdc++3.4 gcc3.4 gcc3.3

gcc3.3 is already the newest version.
libstdc++3.3 is already the newest version.

Что-то никак не пойму, как это лечить.
