Not able to install any software from ubuntu software center. There is no response after pressing install button.

The error which I get

Edit 1

New errors after running the command given in the answer.

I tried with sudo too.

A part of the error code

Removing /usr/local/lib/python2.7/dist-packages/setuptools-1.4.1-py2.7.egg Copying setuptools-1.4.1-py2.7.egg to /usr/local/lib/python2.7/dist-packages setuptools 1.4.1 is already the active version in easy-install.pth Installing easy_install script to /usr/local/bin error: /usr/local/bin/easy_install: Permission denied Something went wrong during the installation. See the error message above.

Reset to default

permissions in your python packages are possibly not working , change its permission by using- 

sudo chown -R $USER /usr/local/lib/python2.7/dist-packages/

-Replace USER with your login name, if this doesnt works check the output of -

/usr/lib/ubuntu-sso-client/ubuntu-sso-login

If it throw any error ImportError: No module named pkg_resources

then the reason behind this could be setup tools package has been deleted in my Python environment .to solve this use the following script-

curl https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py | python

hope it will work.

    I agree with @dobey. While it may fix the issue changing permissions in system folders is a bad idea. Plus "fixing" an issue like this does not really get to the root cause
