After the above error happened, I'm getting these on subsequent attempts to do apt-get update / dist-upgrade:

This is likely a duplicate of bug 1764848. Do you have python-ubuntu-sso-client installed? Purging that package should hopefully let you work around this issue.

Wow, that looks *realy* unhappy.

But this requires a *purge*, not a *remove*. Try again with:

sudo apt-get purge python-ubuntu-sso-client

and see if this gets you further along.

Thanks
