Forum Thread: Kali Package Manager Screwed Up

My kali linux installation was working fine about a week ago, but then I had to reinstall it due to accidentally paritioning my hard drive wrong. Now, many packages aren't downloadable using the apt-get install command. For example, when I would type "apt-get install mitmf" kali would say that it couldn't find a package. Whenever I remove a program from the repo, like hashcat, whenever I try to reinstall it, Kali would again say "no package found." Does anybody have a solution?
