I'm not an expert in Ubuntu, so maybe it's a stupid question, but I'm having problems trying to install a software called pyPENELOPE. Following the steps in their site http://pypenelope.sourceforge.net/download.html I tried the comand

sudo dpkg -i /path/python-penelope_0.2.10-1_all.deb

But I've received the error message

Preparing to unpack .../python-penelope_0.2.10-1_all.deb ...
Upgrading pyPENELOPE
Unpacking python-penelope (0.2.10-1) over (0.2.10-1) ...
dpkg: dependency problems prevent configuration of python-penelope:
 python-penelope depends on python-wxgtk2.8; however:
  Package python-wxgtk2.8 is not installed.

dpkg: error processing package python-penelope (--install):

Errors were encountered while processing:
 python-penelope

What I'm doing wrong?

The problem is that sudo dpkg --install filename.deb only identifies dependencies. It doesn't handle those dependencies automatically. You must install the dependencies (in the correct order) yourself.

That's why your output is complaining about "dependency problems": dpkg is telling you that you neglected to install the other package first.

  • Try using sudo apt install ./filename.deb instead. Apt DOES handle dependencies automatically.

  • If you read that dpkg -i instruction somewhere, please ping the author to update their documentation.

However, that won't work either for you due to a SEPARATE coincidental problem: The package python-wxgtk2.8 was dropped from Ubuntu after Ubuntu 14.04.

Seems like you're trying to use very old, unmaintained software. If you encounter problems, we don't provide support for it (sorry).
