Question:
Upgrade to 13.04 has totally messed my system up .

Traceback (most recent call last):

ImportError: cannot import name MAXREPEAT
this is happening for both the real environment as well as for virtual environment .
i tried removing python with
sudo apt-get remove python
and sadly it has removed everything .
now google chrome does not show any fonts .
i am looking for getting things back to work .
help is needed for proper configuring it again.
Answers:
If you are using virtualenvwrapper then you can recreate the virtualenv on top of the existing one (with no environment currently active):
mkvirtualenv <existing name>
which should pull in the latest (upgraded) python version from the system and fix any mismatch errors.
I have just solved that problem on my machine.
The problem was that Ubuntu 13.04 use python 2.7.4. That makes conflict with the Python version of the virtualenv
.
What I do was to re-create the virtualenv
with the new version of python. I think it’s the simplest way, but you can try to upgrade the python version without re-creating all of the virtualenv
.
You don’t need to recreate the environment.
You can upgrade the virtualenv running this command:
virtualenv /PATH/TO/YOUR_OLD_ENV
YOUR_OLD_ENV
folder will be properly upgraded to the version 2.7.4.
