[Tutor] Python 3.2 Install Not Responding To Python Command!!

[Nevins Duret]

Hello Rohan, 

    I can't thank you enough but believe it or not, you guys helped me tremendously on the last posting.  It was basically a symbolic link issue that was reeked havoc on my system.  After reinstating the symbolic link to where I had it as before and deleting the file that the symbolic link created I was able to update, as I was not able to do this before, as a result of python being broken, and then adding the repository link graphically using the update manager!!  Thanks so much for all your help, now I know how to do it through the Terminal!!!

If it's not empty you need to see what is in fact in it and hopefully get rid of it or move it out of the way. Once it's empty, then just delete the /usr/bin/python folder (you'll have to be root or use "sudo") and afterwards either recreate a link to the default python interpreter and/or try the update-alternatives command again. (To manually restore the default python link, first execute "which python2.6" which should output "/usr/bin/python2.6", then execute "sudo ln -s /usr/bin/python2.6 /usr/bin/python" which should restore the link to the default python.  After doing this "update-alternatives" should have less trouble redirecting the /usr/bin/python link.
