ubuntu 12.04 python problem or?

Question

Hi i am trying to fix this for a long time but without success. When i open my zsh terminal i get this error: (terminal is working but error appear)

 Welcome to the world of tomorrow!
virtualenvwrapper_run_hook:12: permission denied: 
virtualenvwrapper.sh: There was a problem running the initialization hooks. 

If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenv has been installed for
VIRTUALENVWRAPPER_PYTHON= and that PATH is
set properly.

I tried few things but... dont know how to solve it. Somehow during looking for a search i found i should post here an output of:

Also when i try to open ubuntu software center absolutly nothing happens. No idea what to do now.

Answer 1

Disclaimer: I do not know anything about the python virtualenv you have installed, but it seems you have the packages in an inconsistent state. Probably a lot of problems arises from the fact that something is failing in your shell startup files and you have an half-baked environment up. So this is a wild guess, you should check with the support of the virtualenv thing you have.

Disclaimer: if you have installed things forcing the installation (you or some script) this can disrupt your system.

I would try to do the following:

1) try to see if it is automatically fixable:

sudo apt-get install -f

2) If this fails, try to see if you have "held" packages:

apt-mark showhold 

3) if you have, un-hold them with:

sudo apt-mark unhold <package name> 

And then repeat the step 1.

After that, probably the best thing you can do is removing all the packages that are creating problems with

sudo apt-get remove <package> 

or even (you have played around with configuration files)

sudo apt-get purge <package>

and then reinstall them with sudo apt-get install. I would do this at least with the packages that give you error:

python-pip python-virtualenv gimp virtualenvwrapper ubuntu-system-service

and probably zsh too --- probably you'll have to remove/rename the .zshrc, .zlogin, .zshenv files too (if some installation script has modified them, reinstalling zsh will not change files in your home dir). Hope this helps...
