How to point /usr/bin/python to python2.6?

Question

I had done something like:

http://paste.ubuntu.com/704579/

I kind of want to undo that one.

While trying to remove virtualbox-ose I get the error saying

Removing virtualbox-ose ...

There is a line which says /usr/bin/python does not match the python default version. It must be reset to point to python2.6

So my question is how to get /usr/bin/python to match the default version (python2.6)?

Answer 1

Assuming you have another version [i.e. 2.7] and also have 2.6 installed, I would do this:

ln -sf /usr/bin/python2.6 /usr/bin/python

Then, python would be a symbolic link to python2.6

This is what you are asking, right? Or am I missing something here.
