Thanks for your report.

Could you please revert python2.7 to the version from the official Ubuntu repository and try again. Thanks.

I'm closing this report because it is not a bug in Ubuntu. Don't hesitate to submit any new bug.

I still have the same problem. I have tried many different solutions, but none worked out for me. Here are my log files:

@Ramy Aboul Naga, please file a new bug instead of reopening an unrelated closed one. Thanks.
