"playonlinux depends on python-wxgtk2.8; however:
Package python-wxgtk2.8 is not installed."
So we try to install python-wxgtk2.8
"The following packages have unmet dependencies:
python-wxgtk2.8: Depends: python (< 2.5) but 2.5.2-0ubuntu1 is to be installed"

I'm not sure what Ubuntu's deal is with Python 2.5.2 and 2.4 that are installed but for some reason it does not like them. Why? What can I do?

- Your computer configuration.
