This question is an exact duplicate of:
After getting a request to install OS updates I waited almost 12 hours, which after being done I ran
grep Version /etc/os-release. It says version 2018.4 but, when I run
uname -a and
uname -r both say 4.17.0. So shouldn't it say 4.18.0? I also had a folder or directory called
kali live and now it is gone.
