Failure of a deb package installation

[Francesco Pietra <chiendarret@gmail.com>]

Hi:
As no clues arrive from the package web site, may I ask if the
following problems may derive from my bad management of the  OS?

Task: install octopus on a multisocket dual-opteron 875, OS = debian
amd64 lenny (octopus is a molecular computational program).


1) downloaded octopus-3.0.1-1.x86_64.rpm.

2) #alien -k --scripts octopus-3.0.1-1.x86_64.rpm (which reported no errors).

3) #dpkg -i octopus-3.0.1-1.x86_64.deb

Selecting previous deselected package octopus.

(Reading database ... 106160 files and directories currently installed).

Unpacking octopus (from octopus-3.0.1-1.x86_64.deb) ...

Setting up octopus (3.0.1-1) ...

dpkg: error processing octopus (--install):
 subprocess post-installation script returned error exit status 2

Processing triggers for man-db ...

Errors were encountered while processing:
octopus

Subsequently, on command

# apt-get update

#apt-get upgrade

1 not fully installed or removed.

Setting up octopus (3.0.1-1) ...

dpkg: error processing octopus (--configure)
  subprocess post-installation script returned error exit status 2
E: Sub-process /usr/bin/dpkg returned an error code (1)

Command

#apt-get -f install

reports now the same error.

Is that an error in the configuration of the program?

Thanks for help
