There are additional Kali sources that can be used, however as a word of caution the repo's on the documentation page are the recommended repos, as adding these additional ones may cause issues down the line. With that in mind, you can try appending your sources.list file with the following:
Code:
deb [arch=i386,amd64,armel,armhf] http://http.kali.org/kali kali-dev main contrib non-free
deb [arch=i386,amd64,armel,armhf] http://http.kali.org/kali kali-dev main/debian-installer
deb-src http://http.kali.org/kali kali-dev main contrib non-free
deb [arch=i386,amd64,armel,armhf] http://http.kali.org/kali kali main contrib non-free
deb [arch=i386,amd64,armel,armhf] http://http.kali.org/kali kali main/debian-installer
deb-src http://http.kali.org/kali kali main contrib non-free
deb [arch=i386,amd64,armel,armhf] http://security.kali.org/kali-security kali/updates main contrib non-free
deb-src http://security.kali.org/kali-security kali/updates main contrib non-free
It's worth a shot if your willing to take the risk. I personally do not know if this will provide terminator or not though as I haven't tried.
