nova client doesn't work on my Debian Wheezy. Every command gives the same error:

ERROR: printt

Here is debug output for 'nova image-list' ('glance index' shows three testing images):

nova --debug image-list

I have the same problem as you describe.

Can you teach me how to downgrade the module? Thank a lot!

Sorry for one thing, the OS is Ubuntu 12.04.

Many thanks :D

When PrettyTable got updated to 0.6 it looks like it removed the "printt" function. A workaround for now is to downgrade PrettyTable to 0.5 to get the client working.

To downgrade the module, you can use the following command:

pip install prettytable==0.5 or easy_install prettytable==0.5

If it was installed system wide you may first need to sudo apt-get remove python-prettytable.

Okay, the fix was to use pip to upgrade python-novaclient and python-glanceclient each of which then upgraded a list of dependencies and this seems stable.
