yum install error File “/usr/bin/yum”, line 30 except KeyboardInterrupt on Cent OS Ubuntu Linux Mint Redhat

This is a common problem if you updated your python distribution to python 3. Normally installed python from source.

 

Unfortunately yum still depend on the python 2

What you need to do is:

$which python

Then navigate normally to:

$cd /usr/bin/

$ll | grep python

and see what is happening:

lrwxrwxrwx    1 root root           9 Feb 22 17:10 python -> python2.6
lrwxrwxrwx    1 root root           6 Nov  9 12:04 python2 -> python
-rwxr-xr-x    1 root root        9032 Jul 10  2013 python2.6

In my case I have already fixed this problem so you can see that my symlink python -> python2.6

if it point to something else then you need to type in:

ln -s python2.6 python

You can use any other version of python you have got installed as long as it is version 2
