Files in /usr/bin are system managed.  A user should not change them.
If you do, you have broken your system.

The error message you report is *not* a bug but a safety mechanism to
guard against users who have broken their systems.

If you desire to use a different version yourself, please set such a
symlink in /usr/local/bin/python.

You can not expect the system packaged software to work with a modified
/usr/bin/python.

Please see these messages:

Title:
  package software-center 4.0.3 failed to install/upgrade: subprocess
  new pre-removal script returned error exit status 1

Status in “python-central” package in Ubuntu:
  Invalid

Bug description:
  GUI update stalled after clicked "Install Updates", so I had to kill
  it.  I think the important thing is that earlier in the week I
  symlinked /usr/bin/python to Python2.6 instead of the installed
  Python2.7: "ValueError: /usr/bin/python does not match the python
  default version. It must be reset to point to python2.7"

  1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
  stav at bluqt:~$ lsb_release -rd
  Description:	Ubuntu 11.04
  Release:	11.04

  2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
  stav at bluqt:~$ apt-cache policy software-center
  software-center:
    Installed: 4.0.3
    Candidate: 4.0.4
    Version table:
       4.0.4 0
          500 http://mx.archive.ubuntu.com/ubuntu/ natty-updates/main i386 Packages
   *** 4.0.3 0
          100 /var/lib/dpkg/status
       4.0 0
          500 http://mx.archive.ubuntu.com/ubuntu/ natty/main i386 Pack

  3) What you expected to happen
  I expected apt-get to upgrade all my packages and exit mornally.

  4) What happened instead
  What happened was that a Python stacktrace was displayed and the program exited with an error status (1)
  stav at bluqt:~$ sudo kill 4626 [update-manager]
  stav at bluqt:~$ sudo apt-get update
  stav at bluqt:~$ sudo apt-get upgrade
