This is the command that actually updates your system. It just fetches the information about the packages. The “apt update” command doesn’t install the new packages or even update the existing packages. Basically, your system checks if there is a new packages available from the Kali Linux servers, or if there is a new version of a package available. This command refreshes the list of repositories on your system. This has confused many as to why there is an “update” command, that is supposed to update the system, then we are also using the “upgrade” command after all is done. Lets look at the two commands I have combined together with the “&” option, “update” and “upgrade”. That’s why it’s called a package manager. The apt command is used to install/remove or update packages i.e. The procedure is the same as updating Debian. So, Ubuntu and Kali Linux both use the Debian’s package management system apt. Kali Linux is based on Debian, just like Ubuntu. We recommend changing this to something more secure later on. In case you are wondering the default password is “toor”, for a fresh Kali install. Normally, you need to be sudo user to run these commands, but in Kali Linux, you are always root. This way you’ll have a better understanding of what you are doing. It’s a combination of two commands: apt update and apt upgrade.ĭon’t worry. If you want to update Kali Linux system, all you need to do is to use the command below: apt update & apt upgrade -y
