Debian is a Linux operating system widely used in web servers, despite being very friendly, we all need a push to understand how it works. As most servers do not have a graphical interface, since it is not recommended or necessary to have it, we have to use the terminal or console to make all the adjustments and installations for it to work. In order to update the software packages on Debian using apt, apt-get or aptitude, we need access as root in the terminal or use the sudo command before each command.
The most modern package manager is apt.
Update with different managers

To do it with aptitude, it is basically the same. Get the latest list of software and update packages:
aptitude update
aptitude upgradeIf we want to know which version, we will update our packages to:
aptitude -V upgradePost-upgrade steps
Cleaning
To clean the downloaded packages according to each manager.
With apt

apt cleanWith apt-get
apt-get -y autoremove

Finally, keeping the packages in our system updated is as important as their installation itself, since security problems are continuously solved, and best of all, improvements come out that could serve us in the future or in many cases increase the efficiency of the program.
