I had earlier few years ago installed nethunter on my Motorola Nexus 6 and Huawei Nexus 6p. I wiped out nethunter on my Nexus 6 by flashing stock Android. now when I try to install apps from app store like nethunter app its asking for root permissions & busy box even after rooting nethunter terminal crashes asking for chroot. Since Kali Linux has officially announced that nethunter works on non rooted devices I don't know why am getting this error, any suggestions are welcome.
