How to replace tk8.6 with tk8.5?

  • 772

The title explains pretty much all I need to do. I need a downgrade from tk8.6 to tk8.5 on 14.04.

There is some niche scientific python based software that I need to use, however it is incompatible with tk8.6 and is compatible with tk8.5; download available here. Ideally I would like a method that poses minimal risk to my system.

Here are some details that might be useful.

me@James:~$ whereis tk
tk: /usr/lib/tk8.6 /usr/include/tk
14.04

    There's no easy way to downgrade tk to 8.5 on 14.04, even if you install tk8.5.

    This method is not recommended as it's basically installing the 13.10 packages version on a 14.04 system.

    First of all, to restore your system, the command to use will be:

    sudo apt-get install blt python-tk

    Now to downgrade to tk8.5:

    1. Install tk8.5:

      sudo apt-get install tk8.5

    2. Download the following debian packages from the 13.10 repo (amd64 in this example but you can choose the i386 for a 32bit system):

    3. Open a terminal where you downloaded the two .deb files and type:

      sudo dpkg -i blt_2.4z-7_amd64.deb python-tk_2.7.4-0ubuntu1_amd64.deb

    4. Now to check if the right version is available to your python interpreter:

      $ python
Python 2.7.6 (default, Mar 22 2014, 22:59:56) 
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import Tkinter
>>> Tkinter.TkVersion

>>> import platform
>>> platform.release()
