[Comm] apt-get upgrade errors

[Serge Cherpatyuk <gray380@mail333.com>]

Коллеги,

есть проблема с сабжем. Установил с диска Junior2.2.
Запустил:

# apt-get update

результат - успешно;

# apt-get install rdesktop

результат - успешно;

# apt-get upgrade

depmod: Can't read /boot/System.map-2.4.20-alt10-up
error: execution of %post scriptlet from
slmdm_kernel-up-2.4.20_2.6.16_i386-alt10 failed, exit
status 1
47: xpdf                    
########################################### [100%]
E: Sub-process /bin/rpm returned an error code (47)

# apt-get check  

Reading Package Lists... Error!
E: There are two or more versions of the package
'slmdm_kernel-up' installed in your system, which is a
situation APT can't handle cleanly at the moment.
Please do one of the following:
1) Keep at most one version of the package in the
system; or
2) If you do want to keep multiple versions of that
package, lookup RPM::Allow-Duplicated in the documentation.

E: Error occured while processing slmdm_kernel-up
(UsePackage2)
E: Problem with MergeList /var/lib/rpm/Packages
E: The package lists or status file could not be parsed
or opened.

Где и что мне теперь починить?

С уважением,
Сергей.
