. Maybe it's a conflict or configuration error for browsers and the Operating System...

José, you've reported this issue against Xorg, the display server, why?

Are you still experiencing this problem? If so mirror or repository problems should *not* be reported in Launchpad - see https://wiki.ubuntu.com/Bugs/FindRightPackage#Ubuntu_mirror_issues

Have you tried changing your download servers?
