i searched alot on the web and couldnt find any help, so i decided to sign up to this forum and search for help here
i have windows 7 and kali linux now on my PC

i'm really new to linux and today i installed kali linux
during the installation of linux, it couldnt find any mirrors for downloading stuff, so i did it without

now, when i want to start the instant messaging service, it says that it cannot get my personal information from server..
and i also cant update with the terminal. i tried "sudo apt-get update" (and the others) but linux always says it cant resolve to :

deb http://http.kali.org/kali kali main non-free contrib
deb http://security.kali.org/kali-security kali/updates main contrib non-free

i hope you can understand my problem, my english isn't the best

-have a nice day
