cozz 2020-04-30 21:24 reporter ~0012707	I have only started the past few months with Kali but looks like you need to amend your sources.list file. Kali.org for info on this. I do not want to give you any commands just in case I give the wrong info, maybe in a few months I can offer more detailed instructions. Someone correct me if i am wrong.

cozz 2020-04-30 21:34 reporter ~0012708	Why give half an answer, someone might correct me if I am wrong /etc/apt$ nano sources.list Add this to file: deb http://http.kali.org/kali kali-rolling main non-free contrib deb http://http.kali.org/kali kali-last-snapshot main non-free contrib deb http://http.kali.org/kali kali-experimental main non-free contrib deb-src http://http.kali.org/kali kali-experimental main non-free contrib deb [arch=ppc64el,amd64,arm64] http://mariadb.mirrors.ovh.net/MariaDB/repo/10.3/ubuntu bionic main deb-src [arch=ppc64el,amd64,arm64] http://mariadb.mirrors.ovh.net/MariaDB/repo/10.3/ubuntu bionic main Again just check with someone with a bit more experience.

cozz 2020-04-30 21:35 reporter ~0012709	Correction, sorry!! /etc/apt/ nano sources.list

sbrun 2020-05-01 08:39 manager ~0012712	Yes your source.list is not correct. You can find the official documentation here: https://www.kali.org/docs/general-use/kali-linux-sources-list-repositories/ By default your source list should contain only (see section "Default Network Repository Value") : deb http://http.kali.org/kali kali-rolling main non-free contrib Please note: if you add other repo (like http://mariadb.mirrors.ovh.net/***) you might break your system.
