It is important to update your server at certain intervals. Any program can have security vulnerabilities, so that computer code can be executed by strangers on your server.
Therefore, in this article we will show you how to update the server and the installed packages.
First, log in to your server via SSH.
Debian
Step 1: Update package lists
apt-get update
Step 2: Update packages
apt-get -y upgrade
If you are asked if you want to overwrite a configuration file, select „Install the package maintainers version“ if you have not deliberately changed anything in it.
If you are prompted to select a hard disk for the boot process, select (spacebar) /dev/sda1.
Should you receive an APT error: This must be accepted explicitly before updates for this repository can be applied – we have already linked the solution.
Step 3: Update distribution
apt-get -y dist-upgrade
CentOS
yum update
If you get stuck, the support can install the updates for you.
