Kali Linux ppa:repository

How can I remove repositories in Kali Linux? I have tried sudo add-apt-repository --remove ppa:whatever/ppa But I don't know how to apply this to: Ign:1 //ppa.launchpad.net/noobslab/themes/ubuntu oneiric InRelease Ign:2 ://ppa.launchpad.net/alecive/antigone/ubuntu oneiric InRelease error:3 ://ppa.launchpad.net//ubuntu oneiric InRelease 403 Forbidden [IP: 91.189.95.83 80] Read:4 ppa.launchpad.net/noobslab/themes/ubuntu oneiric Release [9 759 B] Read:5 ppa.launchpad.net/alecive/antigone/ubuntu oneiric Release [9 737 B] Read:7 ppa.launchpad.net/noobslab/themes/ubuntu oneiric Release.gpg [316 B] Good:6 ftp.acc.umu.se/mirror/kali.org/kali kali-rolling InRelease Read:8 ppa.launchpad.net/alecive/antigone/ubuntu oneiric Release.gpg [316 B] Ign:7 ppa.launchpad.net/noobslab/themes/ubuntu oneiric Release.gpg Ign:8 ppa.launchpad.net/alecive/antigone/ubuntu oneiric Release.gpg Reading packagelists… Finished
