When the Install Updates button is pressed in the Update Manager, the Update Manager freezes.

Screenshot for explaining the issue

Update and upgrade did not solve the issue.

I am getting the following error message:

Try running the following commands as an alternative:

sudo apt-get update
sudo apt-get upgrade

That will run the updates for you, maybe after those are run your update manager will work.

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.
