sudo apt-get install python-scipy on an Ubuntu 12.10 machine, I get this:
Reading package lists... Done Building dependency tree Reading state information... Done 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. The following information may help to resolve the situation: The following packages have unmet dependencies: python-scipy : Depends: python-numpy (>= 1:1.6.1) but it is not going to be installed Depends: python-numpy-abi9 Depends: libgfortran3 (>= 4.6) but it is not going to be installed Depends: liblapack3 but it is not going to be installed or liblapack.so.3 or libatlas3-base but it is not going to be installed E: Unable to correct problems, you have held broken packages.
Do you have any idea on how to solve this?
