unsigned content in Android repository

[Chatoyer]

I had followed this howto: http://www.howtoforge.com/installing....04-desktop-p2

I'd used the secure site of Google's repository.

Ubuntu's release is 10.04. Eclipse issues this warning:

Warning: You are installing software that contains unsigned content. The authenticity or validity of this software cannot be established. Do you want to continue with the installation?

Is there a legitimate reason for this? Ought I use the repository, or find another?

Thank you very much for your time and attentions.
