Well. Yep. Wanted a fresh start because I was having dependency confusions, so I ran "whereis python" and literally erased all of the files and directories that came up. Then when I go to run apt-get install python I of course get lots of errors. Is there a way to reinstall python on ubuntu without just doing a clean wipe?

Here is the output of trying to install python binary:

root@ubuntu14-server:/home/kpoole# apt-get install python

  • python : Depends: python2.7 (>= 2.7.5-1~) but it is not going to be installed. I think your previous dependency conflicts are still troubling you. Can you also give output of dpkg -l | grep python – cnvzmxcvmcx Dec 26 '14 at 19:35

In the future don't do this. Do not manually remove (or otherwise mess with) any files installed via package management tools (unless they are explicitly set up for this like configuration files, etc.).

That being said if you are unable (and it looks like this might be the case) to use apt-get to recover from this situation because there are parts of the process that expect that python is already installed then you have a few options (not all of which will necessarily work).

You can fetch the python (and related) .deb files manually and attmempt to use dpkg to install them manually (you'll need to resolve the dependency order manually to make sure this works correctly). Something like:

apt-get download python2.7-minimal ## at least this package is necessary
sudo touch /usr/bin/python2.7 && sudo chmod +x /usr/bin/python2.7
sudo dpkg --unpack python2.7-minimal*

You should check for other missing binaries, like pycompile, and apply the same solution.

After this, is recommendable to check the dpkg database looking for non configured, half-configured and just unpacked packages:

sudo dpkg --check

Read the messages and apply fixes, but normally it would ask for sudo dpkg --configure -a. An sudo apt-get -f install could help depending the situation.

You might also be able to use an installation media recovery mode (or reinstallation) to fix this.

Is there a way to reinstall python on ubuntu without just doing a clean wipe?

Yes. Re-install without formatting.

It will also be the quickest method fixing this since you probably already have a Live DVD.

    Reinstalling ubuntu seems a little overdone in this case. – ike Dec 26 '14 at 14:04

    Since almost everything depends on python and "apt" will no longer work (due to python dependencies) any other method will take a lot longer. A re-install w/o format takes about 10, 15 minutes on a current machine. @ike – Rinzwind Dec 26 '14 at 14:06

    apt should work for other packages, just not python. It's not too difficult to fix this by reinstalling each package. – ike Dec 26 '14 at 14:07

    Deleting a system binary can be cataclysmic, but is not the end of the world. You can remove rm and recover it easily. Python is just a walk in the park. – Braiam Dec 26 '14 at 19:03

Open a terminal and type the following commands:

First, try

sudo apt-get -f install 

If that doesn't work, try

sudo dpkg --configure -a 

If you are still left with problems, run

sudo apt-get install --reinstall python python-chardet python-colorama python-distlib python-django python-django-tables2 python-six python-html5lib python-lxml python-minimal python-pkg-resources python-setuptools python-urllib3 python-requests python-pip python-virtualenv

As a last resort, you might need to remove these packages with the following command and then reinstall these packages using the above command. If this is the case, you will need to pay very close attention. There will be a list of packages uninstalled with the following command. You will need to copy this list and paste it into gedit. With gedit open and the list of packages pasted into gedit, press ctrl + h and enter \n followed by two spaces in "Search for" and one space in "Replace with" to remove all the paragraphs and extra spaces before clicking replace all so that your list contains a list of packages separated only by single spaces.

sudo apt-get purge python-chardet python-colorama python-distlib python-django python-django-tables2 python-six python-html5lib python-lxml python-minimal python-pkg-resources python-setuptools python-urllib3 python-requests python-pip python-virtualenv

Finally, run: sudo apt-get install and paste in the list of packages from gedit to reinstall everything.

  • I'm almost certain that all the python-* packages are included in the python meta-package. OP would not need to establish and maintain a list of packages to (un)/install. apt-get install --reinstall python should cover it. – amanthethy Dec 26 '14 at 5:14
  • @amanthethy the "list" I mention is the hundreds of other packages that may also be uninstalled such as unity, all the scopes, accounts manager etc ... Also, I can name a few that are not included such as python pip for example. – mchid Dec 26 '14 at 5:16

    No, it won't hurt anyone - aside from the odd carpel tunnel - but it is unnecessary. Also, python-pip is a package manager for python programs. Its an application built using python and not a feature of the language itself. – amanthethy Dec 26 '14 at 5:20

You should remove each package that gives you difficulties, then reinstall them.

See https://askubuntu.com/a/32899/176376 for removal without removing dependancies.

sudo dpkg -r --force-depends "package"

sudo apt-get install "package"

You should remove all of the problem ones first, and then install them again.

Run a sudo apt-get install -f and sudo dpkg --configure -a every few commands.

I see you have errors like this:

python2.7: not found

It means the python 2.7 executable cannot be found. I have used these command to find the package containing it (that would probably not work on your broken system, however)

$ which python2.7
/usr/bin/python2.7
$ dpkg -S /usr/bin/python2.7
python2.7-minimal: /usr/bin/python2.7

You need to reinstall it, but first you need to go through its dependencies. Use this commands to list them:

$ apt-cache depends python2.7-minimal
python2.7-minimal
  Depends: libpython2.7-minimal
  Depends: zlib1g
  PreDepends: libc6
  Suggests: binfmt-support
    binfmt-support:i386
  Recommends: python2.7
  Conflicts: binfmt-support
  Conflicts: binfmt-support:i386
  Replaces: python2.7
  Replaces: python2.7:i386
  Conflicts: python2.7-minimal:i386

libpython2.7-minimal is probably damaged. So I recommend you to first issue:

sudo apt-get install --reinstall libpython2.7-minimal

then:

sudo apt-get install --reinstall python2.7-minimal

and then hopefully your

sudo apt-get -f install

will succeed.

That's expected behaviour. Deleting files is not the same as uninstalling a package or program.

You've deleted all the python related stuff from your install, but your package manager doesn't know this. When you go to install Python again, apt expects all those files to still be there and doesn't bother trying to re-download them. As far as apt is concerned, all of python is still installed; You never told it otherwise.

You can try the following to attempt to correct this:
sudo apt-get install --reinstall python

In the future, uninstall packages using apt-get remove or apt-get purge or graphically from the Ubuntu Software Centre.

    A purge of python un-installs lots of dependencies, where the reinstall will not reinstall all those. – oldfred Dec 26 '14 at 16:36

    You are right just up to the second paragraph. Your method of "correct"ing the problem could just remove most of the packages of OP system. – Braiam Dec 26 '14 at 19:06
  • @Braiam You're right. I took for granted that apt-get remove package can uninstall packages that apt-get install package won't necessarily restore. I've edited, but feel free to correct it if I'm still off. – amanthethy Dec 27 '14 at 7:31
