I've seen some of this problems around but still can't find out what is wrong :/ (using 12.04 btw)

Any help is really appreciated

Answer 1

The dash after http:// looks weird: http-://ppa.launchpad.net/ferramroberto/java/ubuntu/dists/precise/main/source/Sources

Also, those PPAs seem to have been removed:

http://ppa.launchpad.net/unity-team/hud/ubuntu/dists/

there should be a precise directory here but it's empty? I suggest you check with the people who maintain these PPAs for replacements, but it seems to me like they're not working anymore and you should remove them.

This question has good information on how to remove non-working PPAs: How can I fix a 404 Error when using a PPA or updating my package lists? (taken from Jorge's comment).
