To update Kali, first ensure that /etc/apt/sources.list is properly populated: :~$ cat /etc/apt/sources. Kali has a release four times a year, and follows a loose quarterly schedule. For this reason, it is a good idea to follow the Kali Twitter, or check the Kali website every few months. If you are using last-snapshot, you will not receive updates until we release the next version of Kali for that year. As Kali is a rolling release, once in a while issues will sneak into rolling and may break a tool that is needed. The sudo apt-get upgrade command downloads and installs the updates for each outdated package and dependency on your system.

However, a good practice is that you ensure all tools work before an engagement and during that engagement you should not update.

If you need a new version of a tool, or hear about a security update, that may speed up the timetable.
