+1 They are! (Closed)

It's the 2017.2 release.And what can I do?Since the newer version won't work for me.

Kali is going the rolling update route which explains why older builds source lists do not work.

Not sure why you would do that--have you seen https://docs.kali.org/introduction/s...use-kali-linux ?

I would suggest you install a recent copy of Kali and all your problems will be gone. ;)
