I have trouble with sage manifold. Please help to fix this problem.

When I type

Manifold(2, 'M')

it shows

NameError                                 Traceback (most recent call last)
<ipython-input-1-9ad1037f0edd> in <module>()

----> 1 Manifold(Integer(2), 'M')

NameError: name 'Manifold' is not defined

I installed sage manifold using

sudo bash sm-install.sh

I installed sage using the following commands:

sudo apt-add-repository -y ppa:aims/sagemath
sudo apt-get update
sudo apt-get install sagemath-upstream-binary

Hi,

Unfortunately, due to some change in the SageMath PPA (Sage sources are no longer shipped with the Ubuntu package), it is no longer possible to install SageManifolds in this way, because SageManifolds needs Sage sources to be build, cf. this discussion.

So for the time being, if you want to install SageManifolds, install first Sage in your home directory (not system-wide!) from a Linux binary that you can download from here (do not select the PPA method). Then follow these instructions.
