Having Trouble Getting Repositories and Boot Kernel for Kali Linux 2.0

I've installed Kali Linux 2.0 using a USB. I can't seem to figure out how to fix the partitions and how to get the repositories that I will need. I've tried 5 times already and nothing is working. All I can do is use the internet. I can't use any of the applications because it won't allow me to install any of the applications from the terminal. Every time I try to install something i get an error message saying not found. Can anyone help me with this issue?

Please try running "apt-get update" and then installing the software again.
Then post the full output of those commands and any error messages you receive.
