I have Ubuntu 10.04(Gnome) and since the last update, I no longer can update or open the manager and many other programs. On the console when I try to update it says http://ppa.launchpad.net/hakermania/format-junkie/ubuntu/dists/lucid/main/binary-i386/Packages.gz 404 Not Found
It also appears that I have 904 files outdated. I have tried so many commands, but any one works duo this error. Can some one help me?
