Hi, Luis!

I have just moved your previous question to Ubuntu project (https://answers.launchpad.net/ubuntu/+question/696397), since this space here is intended for questions about Launchpad itself.

I will close this question here, so you can follow the answers in https://answers.launchpad.net/ubuntu/+question/696397, avoiding duplication, ok?

Can you help with this problem?
