OS version:Ubuntu 12.04 LTS

Hey all, I recently started programming in python, so I went to download python 3.0, and it appears I have ruined all python files on my installation, whenever I try to run anything with python I get this error:

chris@chris-Modena-M101:~$ python
bash: /usr/bin/python: No such file or directory
chris@chris-Modena-M101:~$

I tried to install Python 3 again it said it was done, but I still get this error. Please can anyone help me? This is really bugging me as I cant use many defalt ubuntu programs because of this.

Thanks for reading.

Did you happen to remove the python2 packages? The python3 packages do not touch /usr/bin/python at all. Perhaps you just need to re-run dpkg-reconfigure python*. – dobey Aug 23 '12 at 17:41

You don't run python3 by running python. You run it by running python3 or python3.2 at this time.

If you removed python2/2.7, then you shouldn't have a /usr/bin/python. Don't remove python2. They happily co-exist.

If you want python the command back:

  1. apt-get -f --reinstall install python python-minimal python2.7 python-doc python-tk
  2. alias python to python3
    or
  3. softlink python to python3

The preferred method would be to reinstall the python pseudo-package.

note: python doesn't appear to be integrated into update-alternatives... I just checked.

Just tried /sigh* now this: chris@chris-Modena-M101:~$ sudo apt-get -f install python Reading package lists... Done Building dependency tree Reading state information... Done python is already the newest version. You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: jockey-gtk : Depends: jockey-common (= 0.9.7-0ubuntu7.1) but 0.9.7-0ubuntu7 is to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution). chris@chris-Modena-M101:~$ – Chris Aug 23 '12 at 18:30

You're not running stock 12.04 or you did something strange like run an edgers ppa that broke things. – RobotHumans Aug 23 '12 at 18:32
