The command:

sudo apt-get install -y ca-certificates

does the following:

1. sudo: Runs the command with superuser (administrator) privileges, which is necessary to install system-wide packages.

2. apt-get install: This instructs the package manager (apt-get) to download and install the specified package(s) from the system's repository.

3. -y: Answers "yes" to all the prompts that would normally require user confirmation during the installation process, making the command non-interactive.

4. ca-certificates: This is the name of the package being installed. The ca-certificates package contains a collection of digital certificates. These certificates are used to verify the authenticity of SSL/TLS connections (e.g., when accessing secure websites or services). Installing this package ensures that the system trusts commonly recognized Certificate Authorities (CAs).

Summary:

This command installs the ca-certificates package on a system, ensuring it has an updated set of trusted certificate authorities for validating secure communications.
